THS4031IDGNR

Instrumentation, Op Amps, Buffer Amps Overview

The THS4031IDGNR is a single-channel high-speed voltage-feedback operational amplifier manufactured by Texas Instruments. It features a gain-bandwidth product of 120 MHz and a slew rate of 100 V/us. The device operates within a supply voltage range of 9 V to 32 V, consuming 8.5 mA of quiescent current per channel. Key electrical specifications include an input offset voltage of 2 mV, input bias current of 6 uA, and low input voltage noise density of 1.6 nV/sqrt Hz. It provides a typical open-loop voltage gain of 98 dB and a common-mode rejection ratio of 95 dB. The component supports output currents up to 90 mA and functions reliably across an industrial temperature range from -40 C to +85 C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the complete part number including the suffix 'IDGNR' to ensure correct package type and reel quantity. Confirm RoHS compliance status through official manufacturer documentation before integration. Check for specific moisture sensitivity level requirements during storage and handling procedures. Ensure ordering quantities match available packaging formats such as tape and reel configurations.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when high bandwidth and low noise are critical requirements for voltage feedback applications. Compare against the THS4041 if higher slew rates are needed, or consider the THS4531 series for fully differential architectures. Evaluate power dissipation limits in MSOP-8 packages under maximum load conditions. Verify that the 120 MHz gain-bandwidth product aligns with system frequency response targets.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the THS4031 family of high-speed operational amplifiers from Texas Instruments. It shares architectural similarities with other members like the THS4031CDR but differs in package configuration and commercial/industrial temperature ratings. The IDGNR designation specifically indicates the MSOP-8 surface-mount package variant optimized for space-constrained designs.
