THS4120IDGKR

Instrumentation, Op Amps, Buffer Amps Overview

The THS4120IDGKR is a fully differential CMOS amplifier from the Texas Instruments THS4120 series. It features a gain-bandwidth product of 100 MHz and a slew rate of 55 V/us. The device operates on a supply voltage between 3 V and 3.5 V, drawing 11 mA of quiescent current. Key electrical parameters 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 functions within a temperature range of -40°C to +85°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix IDGKR against official datasheets to confirm the reel packaging format and tape-and-reel quantity specifications. Ensure the ordering part number matches the required industrial temperature grade and package variant. Cross-reference manufacturer documentation to validate RoHS compliance status and pinout configurations before finalizing procurement orders.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a single-channel fully differential amplifier with 100 MHz bandwidth is required. It is suitable for designs needing low input bias current and rail-to-rail performance under a 3 V to 3.5 V supply. Consider the VSSOP-8 package constraints and thermal dissipation limits relative to the application's power budget and space requirements.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the THS4120 family of fully differential amplifiers manufactured by Texas Instruments. It shares core architectural similarities with other variants in the series, differing primarily in packaging and reel configuration. The IDGKR suffix denotes the specific surface-mount VSSOP-8 package delivered in a tape-and-reel format for automated assembly processes.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Compatible substitutes within the same family include THS4120IDGK and THS4120IDGN. Verify that alternative packages maintain identical pinouts and electrical characteristics to ensure direct compatibility without circuit redesign.
