THS4531AIDR

Instrumentation, Op Amps, Buffer Amps Overview

The THS4531AIDR is a single-channel fully-differential amplifier from the THS4531A series, manufactured by Texas Instruments. It operates within a supply voltage range of 2.5 V to 5.5 V and consumes 250 uA of quiescent current. Key electrical specifications include a gain-bandwidth product of 27 MHz, a slew rate of 220 V/us, and an input offset voltage of 400 uV. The device features rail-to-rail input and output capabilities, with a common-mode rejection ratio ranging from 90 dB to 116 dB. It provides an output current of 50 mA per channel and has an input bias current of 315 nA. The component is housed in an SOIC-8 package and supports operation temperatures from -40 C to +125 C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'A' indicates the enhanced performance variant compared to standard THS4531 devices. Confirm the 'IDR' suffix corresponds to the SOIC-8 tape-and-reel packaging format. Ensure compatibility with the required thermal management for the SOIC-8 package in the target application environment. Check for moisture sensitivity level requirements during storage and handling.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this part when both low power consumption and high-speed differential signaling are required. The THS4531AIDR offers superior DC accuracy with a 400 uV offset voltage compared to the standard THS4531. Consider the SOIC-8 package for surface-mount assembly constraints. Evaluate the 50 mA output drive capability against load requirements.

Instrumentation, Op Amps, Buffer Amps Part Context

This component belongs to the THS4531A family of ultra-low power fully-differential amplifiers. It serves as an upgraded version of the THS4531, offering improved DC precision while maintaining similar AC performance characteristics. The family is designed for battery-powered and portable applications where power efficiency is critical alongside signal integrity.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The THS4531AID is the tube-packaged equivalent of this reel-part. The THS4531IDR is a standard variant with higher offset voltage (1 mV) but otherwise similar AC specs.
