INA592IDR

Instrumentation, Op Amps, Buffer Amps Overview

The INA592IDR is a high-precision, wide-bandwidth e-trim difference amplifier manufactured by Texas Instruments in an 8-pin SOIC package. It integrates a precision operational amplifier and a matched resistor network to provide fixed gains of 1/2 V/V or 2 V/V. Key electrical specifications include a maximum input offset voltage of 40 µV, a gain error of ±0.03%, and a common-mode rejection ratio (CMRR) of at least 88 dB. The device operates on single supplies from 4.5 V to 36 V or dual supplies from ±2.25 V to ±18 V, with a quiescent current of 1.1 mA per amplifier.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix 'IDR' corresponds to the SOIC-8 package and tape-and-reel shipping configuration as defined in the manufacturer's official documentation. Confirm that the component meets the required RoHS compliance standards and check for any recent production data updates or package option addendums that may affect availability or mechanical dimensions prior to finalizing procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select the INA592IDR when a fixed gain difference amplifier is required with high precision and wide bandwidth. Ensure the application utilizes a supply voltage within the 4.5 V to 36 V range. Consider the 8-pin SOIC package constraints if space is limited. Verify that the required gain configuration (1/2 or 2) matches the pin connections specified in the datasheet to ensure correct operation.

Instrumentation, Op Amps, Buffer Amps Part Context

The INA592 belongs to Texas Instruments' family of high-precision difference amplifiers. Unlike discrete solutions requiring expensive external resistor networks, this device integrates the necessary precision resistors internally. This integration ensures excellent tracking of temperature coefficients (TCR), maintaining gain accuracy and common-mode rejection over the specified operating temperature range of -40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Consult the Device Comparison Table in the official datasheet for alternatives such as the INA159, INA137, or INA132. Verify that substitute devices meet the specific gain requirements (1/2 or 2) and package compatibility before implementation.
