THS4121IDGNR

Instrumentation, Op Amps, Buffer Amps Overview

The THS4121IDGNR is a fully differential CMOS amplifier manufactured by Texas Instruments. It features a gain-bandwidth product of 100 MHz and a slew rate of 55 V/us. The device operates on a single supply voltage ranging from 3 V to 3.5 V, with a typical operating current of 11 mA. Key electrical specifications include a common-mode rejection ratio (CMRR) of 96 dB, an input bias current of 1.2 pA, and an input offset voltage of 8 mV. Each channel provides an output current capability of 25 mA. The component supports rail-to-rail input and output operation and is housed in an MSOP-8 package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'GNR' corresponds to the MSOP-8 package and tape-and-reel packaging configuration as documented in the official datasheet. Confirm that the ordering part number matches the exact pinout and thermal characteristics required for the target PCB layout. Ensure compliance with RoHS directives if applicable to the deployment region.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when low power consumption and high bandwidth are required in a small form factor. The THS4121IDGNR is appropriate for designs needing rail-to-rail I/O within a narrow 3V to 3.5V supply range. Consider the MSOP-8 package constraints for thermal management and board space compared to larger packages like SOIC or HVSSOP found in other series members.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the THS4121 family of fully differential amplifiers designed for low-power, high-speed applications. It is distinct from higher-voltage variants such as the THS4130 or THS4140, which support wider supply ranges up to 33V. The THS4121 is optimized for single-supply operation at 3.3V, making it suitable for modern low-voltage digital systems.
