OPA4171AIDR

Instrumentation, Op Amps, Buffer Amps Overview

The OPA4171AIDR is a quad general-purpose operational amplifier manufactured by Texas Instruments. It features a gain-bandwidth product of 3 MHz and a slew rate of 1.5 V/us. The input offset voltage is 1.8 mV, with an input bias current of 15 pA. Operating on a supply voltage range from 2.7 V to 36 V, it draws a quiescent current of 475 uA. Each channel provides an output current of 25 mA. The device offers a common-mode rejection ratio of 120 dB and an input voltage noise density of 14 nV/sqrt Hz. It is housed in a 14-SOIC package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'IDR' corresponds to the 14-SOIC tape-and-reel packaging configuration. Confirm AEC-Q100 qualification status if automotive reliability is required. Check moisture sensitivity levels for proper storage and handling procedures during assembly. Ensure the operating temperature range meets the -40°C to +125°C requirements of the target environment.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a quad amplifier with rail-to-rail performance is needed alongside low power consumption. Compare against the OPA4170 series if lower quiescent current is prioritized over bandwidth. Consider the SOIC-14 package constraints for PCB layout. Verify that the 3 MHz bandwidth and 1.5 V/us slew rate are sufficient for the signal frequencies involved.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the OPAx171 family of low-power, high-speed operational amplifiers. It shares electrical specifications with the single (OPA171) and dual (OPA2171) channel variants, allowing for design flexibility across different channel counts. The family is designed for applications requiring good offset, drift, and bandwidth characteristics while maintaining low quiescent current.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The OPA4171AID is the tube-packaged equivalent of the same device. The OPA4171AIPW is the TSSOP-14 pin-compatible alternative. For lower power requirements, the OPA4170AIDR offers similar form factor but reduced bandwidth.
