Introduction

AI Translation

The THS4531A is a low-power, fully differential operational amplifier with an input common-mode range that extends below the negative supply rail and rail-to-rail output. This device is designed for low-power data acquisition systems and high-density applications where energy consumption and power dissipation are critical. The device features precise output common-mode control, enabling DC coupling when driving analog-to-digital converters (ADCs). Coupled with an input common-mode range that extends below the negative supply rail and rail-to-rail output, this control allows easy connection of single-ended ground-referenced signal sources to successive approximation (SAR) and delta-sigma (ΔΣ) ADCs using only a single 2.5V to 5V supply. The THS4531A is also a useful tool for general-purpose, low-power differential signal conditioning applications. The THS4531A can operate over an extended industrial temperature range from -40°C to +125°C.
