OPA192IDR

Instrumentation, Op Amps, Buffer Amps Overview

The OPA192IDR is a single-channel precision operational amplifier from Texas Instruments, utilizing e-trim technology for high accuracy. It features rail-to-rail input and output capabilities, supporting supply voltages from 4.5 V to 36 V. Key electrical specifications include a maximum input offset voltage of 5 µV, an input bias current of 5 pA, and a gain-bandwidth product of 10 MHz. The device delivers a slew rate of 20 V/µs and can source up to 65 mA per channel. It operates within a temperature range of -40°C to 125°C and is housed in an 8-SOIC surface-mount package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the complete part number including suffixes such as 'DR' to confirm the tape-and-reel packaging format. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the operating temperature range aligns with your system's environmental specifications. Cross-reference the datasheet revision date to ensure compatibility with your design constraints.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when low offset voltage and drift are critical alongside rail-to-rail performance. Compare against the OPA191 for lower power consumption or the OPA180 for different noise characteristics. Consider the 10 MHz bandwidth limit for high-speed applications. Evaluate the 65 mA output drive capability against load requirements. Verify that the 8-SOIC package fits your PCB layout constraints.

Instrumentation, Op Amps, Buffer Amps Part Context

The OPA192 belongs to Texas Instruments' e-trim precision amplifier family, designed for applications demanding exceptional DC accuracy. It complements other devices like the OPA191 and OPA180 within the portfolio. The 'IDR' suffix specifically denotes the SOIC-8 package variant supplied in reel packaging. This series targets markets where long-term stability and minimal calibration are essential.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct pin-compatible alternatives within the same family include the OPA192ID (tube packaging). For similar performance with different trade-offs, consider the OPA191IDR for lower quiescent current or the OPA180IDR for lower voltage noise density. Verify that any substitute meets the specific offset voltage and drift requirements of the original design.
