Description
•
•
•
The TPA186x series of amplifiers are the newest highsupply voltage amplifiers with 30-μV low offset, low noise,
and stable high-frequency response. They incorporate
3PEAK’s proprietary and patented design techniques to
achieve excellent AC performance with 6-MHz bandwidth,
5-V/μs slew rate, and low distortion while drawing only
1.4-mA quiescent current per amplifier. The input commonmode voltage range extends to V−, and the outputs swing
rail-to-rail.

Supply Voltage: 4.5 V to 40 V or ±2.25 V to ±20 v
Offset Voltage: ±30 μV Maximum
Differential Input Voltage Range to Supply Rail, can
Work as Comparator
Input Rail to −VS, Rail-to-Rail Output
Drive Any Capacitive Load
Bandwidth: 6 MHz, Slew Rate: 5 V/μs
Excellent EMI Suppress Performance: 85 dB at 1 GHz
The TPA186x has an over-temperature protection feature
to guarantee chip safety. The output of the TPA186x will
enter high impendence when the die temperature reaches
around 170°C and will recover the function when the die
temperature is down to around 150°C. The product has a
very small power temperature coefficient, which is helpful
to temperature-sensitive applications.

(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. Exposure
to any Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime.
(2) The inputs are protected by ESD protection diodes to the negative power supply. If the input extends to more than 300
mV beyond the negative power supply, the input current should be limited to less than 10 mA.
(3) A heat sink may be required to keep the junction temperature below the absolute maximum. This depends on the power
supply voltage and how many amplifiers are shorted. Thermal resistance varies with the amount of PC board metal
connected to the package. The specified values are for short traces connected to the leads.

40-V, 6-MHz, Zero-Drift Op Amps
Detailed Description
Overview
The TPA186x series op amps can operate on a single-supply voltage (4.5 V to 40 V), or a split-supply voltage (±2.25 V to
±20 V), making them highly versatile and easy to use. The power-supply pins should have local bypass ceramic capacitors
(typically 0.01 μF to 0.1 μF). Parameters that can exhibit variance with regard to operating voltage or temperature are
presented in the Typical Performance Characteristics.

Application and Implementation
Note
Information in the following application sections is not part of the 3PEAK’s component specification and 3PEAK does not
warrant its accuracy or completeness. 3PEAK’s customers are responsible for determining suitability of components for
their purposes. Customers should validate and test their design implementation to confirm system functionality.
Application Information
Low Side Current Sensing Application
Figure 18 shows the device configured in a low-side current sensing application. The low-side current sensing method
consists of placing a sense resistor between the load and the circuit ground. The voltage dropping across the resistor is
amplified by different amplifier circuits with the device. The VREF can be used to add bias voltage to the output voltage.
Particular attention must be paid to the matching and precision of R1, R2, R3, and R4, to maximize the accuracy of the
measurement.
Figure 18. Low-Side Current Sensing Application
Power Supply Recommendations
Place 0.1-μF bypass capacitors close to the power supply pins for reducing coupling errors from the noisy or high-impedance
power supplies.
