DESCRIPTION
A2TPMI Ô
The PerkinElmer A2TPMI is a versatile infrared thermopile sensor with an integrated configurable ASIC for signal processing and ambient temperature compensation. This integrated infrared module senses the thermal radiation emitted by objects and converts this to a analog voltage. The A2TPMI can be delivered fully factory calibrated and adapted to the customer specification, as well as customer programmable via the serial interface. In the pre-calibrated version, only three pins are necessary for operation: object output voltage, 5V supply voltage, and ground. As described in this specification, the temperature accuracy of the fully adjustable integrated circuit outperforms that of the previous PerkinElmer thermopile modules with discrete components on pcb, because the A2TPMI features an offset correction of the amplifier and a factory calibrated ambient temperature sensor. This makes the A2TPMI a versatile, compact and high precision device. Due to the internal digital signal processing and 8 bit resolution of the internal control registers the 2 A2TPMI has improved accuracy for adjustment and improved performance. E PROM technology allows unlimited changing of the configuration. For amplification of the highly sensitive thermopile signal in the micro- to millivolt range, a high resolution programmable low noise chopper amplifier is provided. An adjustable high precision ambient temperature sensor followed by a signal processor, offers an accurate compensation signal with polynomial characteristics that perfectly matches to that of the thermopiles output. Adding of these signals results in an ambient independent object temperature signal over a large temperature range, which still can be adapted / scaled to customer needs due to flexible offset and postgain adjustment facilities of the device. The two configurable comparators of the A2TPMI, that can alternatively be used, enhance the functionality. This allows to employ the A2TPMI as an temperature dependent switch for alarm purposes. Threshold temperatures and the hysteresis is free programmable for both comparators. Due to integration of sensor and electronic in a compact TO 39 housing, the A2TPMI is robust and insensitive to environmental influences like pcb contamination (leakage currents), humidity and electromagnetic interference.

VTobj / VTamb Characteristics
The VTobj and the VTamb characteristics of thermopile sensors depends not only on object and ambient temperature but on several other factors like object size to spot size relation, ambient temperature compensation behaviour or optical filter characteristics. Therefore it is not possible to specify a general VTobj and VTamb characteristic. Those characteristics will be specified application specific in a separate customer specification.

General Description
THERMOPILE SENSOR
A2TPMI Ô
The signal voltage, generated by the infrared radiation-sensitive thermopile sensor, is preamplified by a programmable choppered amplifier with 8 bit resolution. Due to the principle of thermopile temperature measurements, the thermopile voltage can be positive or negative depending if the object temperature is higher or lower than the ambient temperature of the A2TPMI. In order to allow signal processing of negative voltages with a single supply system, all internal signals are related to an internal voltage reference (Vref) of nominal 1.225 V, which serves as a virtual analog ground. For offset voltage trimming of the thermopile amplification path, the preamplifier is followed by a programmable trimming stage generating an offset voltage with a resolution of 8 bit. The thermopile voltage shows a non-linear output characteristic versus the object temperature.
AMBIENT TEMPERATURE SENSOR
The temperature of the A2TPMI, respectively the thermopile sensor, is detected by an integrated temperature sensor. This signal will be amplified and signal processed in order to match the reverse characteristics of the amplified thermopile curve, to realize an optimum of ambient temperature compensation after adding the two signals. The characteristics of the temperature sensor signal is adjustable. This adjustment is part of the ASIC production process and will be provided by PerkinElmer. Thus the characteristics of the A2TPMI ambient temperature signal VTamb is always provided fully calibrated.
AMBIENT TEMPERATURE COMPENSATION
The thermopile sensor converts the temperature radiation of an object surface to an electrical signal by means of thermocouples (Seebeck effect). The sensor output voltage is caused by the temperature difference between radiation heated (hot) junctions and cold junctions with a good thermal contact to the housing. In order to deliver an output signal which is only dependent on the object temperature, any change of housing (ambient) temperature has to lead to an appropriate output signal correction. For temperature compensation, the amplified thermopile- and temperature reference signals (VTambint) are added in an adding amplifier stage. The amplification is adjustable in a wide range according to application / customer requirements. The ambient temperature compensated and amplified signal is supplied to the output VTobj. The temperature reference signal or alternatively the bandgap reference voltage is available on a second output pin VTamb. Both outputs are short circuit stable .

CONTROL UNIT / SERIAL INTERFACE
A2TPMI Ô
The operation characteristics of the A2TPMI have to be configured with a set of internal random access registers. All parameters / configurations are permanently stored in E2PROM in parallel, Configuration is usually done during factory calibration and does not need any user input. The control unit offers via serial interface access to all the registers, i.e. the internal parameters of the A2TPMI. The serial interface is a two wire bi-directional synchronous (SDAT, SCLK) type. A2TPMI sensors are in general factory calibrated and therefore there is no need to use the serial interface for standard applications. The SDAT- / SCLK pins are internally pulled up to VDD and can be left unconnected. If the SDAT / SCLK pins will be connected in the application, ensure signal conformity to the serial interface specification. Subsequent undefined signals applied to these pins, may change the configuration and lead to malfunctioning of the sensor. For detailed information about the serial interface refer to application note: A2TPMI Serial Interface description, or contact PerkinElmer application support.
OUTPUT CONFIGURATION
The A2TPMI offers various output configurations, which can be configured via the serial communication interface by means of integrated analog switches. For each output it can be individually selected whether the output operates in ‘Analog mode’ or in ‘Comparator mode’. In ‘Analog mode’ the output signal represents the measured IR radiation, respectively the temperature as an analog DC voltage. In ‘Comparator mode’ the measured IR radiation, respectively the temperature is compared to a programmed threshold. For slowly changing signals an additional hysteresis can be configured. If the measured signal is above the threshold, +5VDC (logical high) is applied to the output. If the measured signal is below the threshold, 0VDC (logical low)is applied to the output. For detailed information about the output configuration refer to application note: A2TPMI Serial Interface description, or contact PerkinElmer application support.

Application Information
AMBIENT TEMPERATURE COMPENSATION
A2TPMI Ô
Because of many physical effects, that influence the non-contact temperature measurement based on infrared radiation, it is difficult to meet the best initial adjustment for a specific application. Therefore some deviations might be found at first measuring. For all applications the optimized solution can be prepared and fixed based on the measurement in the application environment. PerkinElmer is pleased in providing you assistance to find the conditions, which deliver the highest accuracy in your application. The temperature compensation is only working well within a certain ambient temperature range, limited by different device parameters of the thermopile sensor and the temperature reference sensor. The following diagram shows a typical characteristics and is only an example for better understanding of the principle compensation curve. The curve shows the deviation for a correct working of a compensated module.
Temperature Deviation of VTobj vs. Ambient Temperature

Typical Temperature Deviation [K]
2,5 2 1,5 1 0,5 0 -20 -0,5 0 20 40 60 80 100
Ambient Temperature [°C]
The compensation of the module sample in the diagram is adjusted to the best fitting at 20°C to 80°C ambient temperature, but the curve can be shifted in the whole ambient temperature range through the change of A2TPMI parameters.
MEASUREMENT TOLERANCE
The temperature error of the A2TPMI depends on several factors like the emissivity, object temperature, object size to spot size relation, temperature gradients over the sensor housing in the environment, device tolerances and the optimal adjustment of the ambient temperature compensation. The accuracy as specified under VTamb and VTobj characteristics is based on theoretical calculation as well as on statistical evaluation results. The PerkinElmer quality system ensures that all A2TPMIs are calibrated and tested under a certain test conditions in order to guarantee these specifications. However, due to the nature of infrared remote temperature measurements there might occur limits exceeding or deviations in specific application environments. In this case please contact the PerkinElmer application support to help you solving the problem.

OUTPUT SIGNAL
A2TPMI Ô
The A2TPMI amplifiers are realized in chopper amplifier technology. Due to the nature of this technology the output signals VTobj and VTamb incorporate an AC signal of approximately 10 mV peak to peak in the range of 250 kHz. This AC voltage can be suppressed either by an electrical low pass filter or via an additional software filtering. In applications with low resistive load ( > 1Mohm) a simple RC low pass filter as follows can be used to smooth the signal: 500 Ohms

OUTPUT LOAD
Capacitive loads which are applied directly to the outputs reduce the loop stability margin. Values of 100 pF can be accommodated. Resistive load for the outputs should be held as small as possible (i.e. a large load resistance, Rload > 50 kW has to be used) in order to avoid an impact on the temperature signal due to self heating of the module.
RESPONSE TIME
The response time to an object temperature jump depends on the time constant t of the thermopile and the signal processing time of the A2TPMI. The processing of the thermopile signal has a latency time (tlat) of max. 75ms caused by the time required for AD-conversion, DA conversion and signal processing. The following diagram explains the connection of these events

LATCHUP AVOIDANCE
Junction isolated CMOS circuits inherently include a parasitic 4 layer (PNPN) structure which has characteristics similar to a thyristor (SCR). Under certain circumstances this junction may be triggered into a low impedance state, resulting in excessive supply current, which can thermally destroy the circuit. To avoid this condition, no voltage greater than 0.3 V beyond the supply rails should be applied to any pin. In general the ATPMI supplies must be established either at the same time or before any signals are applied to the inputs. If this is not possible the drive circuits must limit the input current flow to maximum 5mA to avoid latchup. In general the device has to be operated with a 100 nF capacitor in parallel to the power supply.
SOLDERING
The TPMI is a lead-free component and fully complies with the ROHS regulations, especially with existing roadmaps of lead-free soldering. The terminations of the TPMI sensor consist of nickel plated Kovar and gold finish. Hand soldering is recommended.
