What are the key features of THS4531AIRUNT?

Ultra-low power consumption with rail-to-rail output (RRO) for battery-powered applications
2.7 MHz 3dB bandwidth with 116 dB common-mode rejection ratio for high-fidelity signal conditioning
Fully-differential architecture with voltage-feedback and internal frequency compensation for stable ADC driving

What is THS4531AIRUNT used for?

The THS4531AIRUNT is designed for driving high-resolution ADCs in portable instrumentation and data acquisition systems where low power consumption is critical. Its fully-differential topology with 90 dB minimum CMRR makes it ideal for rejecting common-mode noise in industrial sensor interfaces and medical monitoring equipment. The -40 to 125°C operating range and compact 10-QFN package suit harsh environment and space-constrained applications.
