ISL28256

® ISL28156, ISL28256 Data Sheet February 27, 2007 FN6154.2 39µA Micropower Single and Dual Precision Rail-to-Rail Input-Output (RRIO) Low Input Bias Current Op Amps The ISL28156 and ISL28256 are micropower precision operational amplifiers optimized for single supply operation at 5V and can operated down to 2.4V. These devices feature an Input Range Enhancement Circuit (IREC) which enables them to maintain CMRR performance for input voltages greater than the positive supply. The input signal is capable of swinging 0.5V above a 5.0V supply (0.25 for a 2.5V supply) and to within 10mV from ground. The output operation is rail-to-rail. The 1/f corner of the voltage noise spectrum is at 1kHz. This results in low frequency noise performance which can only be found on devices with an order of magnitude higher supply current. ISL28156 and ISL28256 can be operated from one lithium cell or two Ni-Cd batteries. The input range includes both positive and negative rail. The output swings to both rails.

The ISL28256 is a dual version without the enable feature. Both devices are designed to operate from single supply (2.4V to 5.0V) or dual supplies (±1.2V to ±2.5V) while drawing only 39μA of supply current per amplifier. This combination of low power and precision performance makes this device suitable for a variety of low power applications including battery powered systems. within one diode beyond the supply rails. They also contain back-to-back diodes across the input terminals. For applications where the input differential voltage is expected to exceed 0.5V, external series resistors must be used to ensure the input currents never exceed 5mA (Figure 35). VIN RIN + RL VOUT FIGURE 35. INPUT CURRENT LIMITING Rail-to-Rail Input/Output These devices feature bipolar inputs which have an input common mode range that extends up to 0.5V beyond the v+ rail, and to within 10mV of the V- rail. The CMOS outputs typically swing to within about 4mV of the supply rails with a 100kΩ load. The NMOS sinks current to swing the output in the negative direction. The PMOS sources current to swing the output in the positive direction. Enable/Disable Feature The ISL28156 offers an EN pin that disables the device when pulled up to at least 2.0V. In the disabled state (output in a high impedance state), the part consumes typically 10µA. By disabling the part, multiple ISL28156 parts can be connected together as a MUX. In this configuration, the outputs are tied together in parallel and a channel can be selected by the EN pin. The EN pin also has an internal pull down. If left open, the EN pin will pull to the negative rail and the device will be enabled by default. Input Protection All input terminals have internal ESD protection diodes to both positive and negative supply rails, limiting the input voltage to 10 FN6154.2 February 27, 2007 ISL28156, ISL28256 The loading effects of the feedback resistors of the disabled amplifier must be considered when multiple amplifier outputs are connected together. where: • TMAX = Maximum ambient temperature • θJA = Thermal resistance of the package • PDMAX = Maximum power dissipation of 1 amplifier • VS = Supply voltage • IMAX = Maximum supply current of 1 amplifier • VOUTMAX = Maximum output voltage swing of the application • RL = Load resistance Using Only One Channel The ISL28256 is a dual op amp. If the application only requires one channel, the user must configure the unused channel to prevent it from oscillating. The unused channel will oscillate if the input and output pins are floating. This will result in higher than expected supply currents and possible noise injection into the channel being used. The proper way to prevent this oscillation is to short the output to the negative input and ground the positive input (as shown in Figure 36). + FIGURE 36. PREVENTING OSCILLATIONS IN UNUSED CHANNELS Current Limiting These devices have no internal current-limiting circuitry. If the output is shorted, it is possible to exceed the Absolute Maximum Rating for output current or power dissipation, potentially resulting in the destruction of the device. Power Dissipation It is possible to exceed the +125°C maximum junction temperatures under certain load and power-supply conditions. It is therefore important to calculate the maximum junction temperature (TJMAX) for all applications to determine if power supply voltages, load conditions, or package type need to be modified to remain in the safe operating area. These parameters are related as follows: T JMAX = T MAX + ( θ JA xPD MAXTOTAL ) (EQ. 1) where: • PDMAXTOTAL is the sum of the maximum power dissipation of each amplifier in the package (PDMAX) • PDMAX for each amplifier can be calculated as follows: V OUTMAX PD MAX = 2*V S × I SMAX + ( V S - V OUTMAX ) × --------------------------R L (EQ. 2) 11 FN6154.2 February 27, 2007 ISL28156, ISL28256 SOT-23 Package Family e1 A N 6 4 MDP0038 D SOT-23 PACKAGE FAMILY MILLIMETERS SYMBOL A A1 SOT23-5 1.45 0.10 1.14 0.40 0.14 2.90 2.80 1.60 0.95 1.90 0.45 0.60 5 SOT23-6 1.45 0.10 1.14 0.40 0.14 2.90 2.80 1.60 0.95 1.90 0.45 0.60 6 TOLERANCE MAX ±0.05 ±0.15 ±0.05 ±0.06 Basic Basic Basic Basic Basic ±0.10 Reference Reference Rev.
