OPA4137PA Application Field And Working Principle

The OPA4137PA is a high performance, low voltage dual operational amplifier from Texas Instruments. It is suitable for a wide variety of linear applications, including instrumentation, buffering, and power supply design. This popular opamp is known for its exceptional performance and wide supply range, making it an ideal choice for precision instrumentation designs.

Classification and Overview

The OPA4137PA is classified under the categories of linear, amplifiers, instrumentation, op amps, buffer amps.

Performance Benefits

The OPA4137PA offers a wide supply range of 4.5V to 17V, as well as an exceptionally low offset voltage of 2.5mV. It also offers a high common-mode rejection ratio (CMRR) of 78dB and low total harmonic distortion (THD) of 0.000015%.

Applications and Features

The OPA4137PA is suitable for a wide variety of linear applications, including instrumentation, buffering, and power supply design. It offers benefit of ultra-low noise performance, high-speed settling and a very low input bias current. It is also able to operate in applications where power supply rejection and noise are of utmost importance. It is also RoHS compliant and offers a typical voltage gain of 96dB.

Work Principle

The OPA4137PA is comprised of two low-voltage, high-precision, internally compensated amplifiers. Each amplifier contains a full complement of gain, offset and power supply pins, and the overall performance is optimized to provide the highest possible CMRR and the lowest distortion. The gain of the two amplifiers is controlled by the single gain-select pin, and the output stage consists of an emitter- or source- follower with a Class A output stage.

In order to minimize distortion, the OPA4137PA contains an internal, fully-differential, wideband, active bootstrapping circuit. This circuit not only minimizes distortion, but also increases power efficiency. Additionally, the high-speed output buffering and input protection network provides fast settling time and excellent protection against electrostatic discharge (ESD) and input cable transients.

Conclusion

The OPA4137PA is a high performance, low voltage dual operational amplifier from Texas Instruments. Its wide supply range and exceptional performance makes it an ideal choice for high precision instrumentation and power supply design. It offers benefit of ultra-low noise performance, high-speed settling and a very low input bias current. Additionally, the internal bootstrapping and output buffering circuitry minimizes distortion, increases power efficiency and provides excellent input protection.
