THS4531AIDGK General Description

The THS4531AIDGK is a low-power, fully differential amplifier specifically designed for low-power data acquisition systems and high-density applications where power consumption and dissipation is critical. With an input common-mode range below the negative rail and rail-to-rail output, this device features accurate output common-mode control that allows for easy interface from single-ended ground-referenced signal sources to successive-approximation registers (SARs) and delta-sigma (ΔΣ) ADCs using only single-supply 2.5-V to 5-V power. Moreover, the THS4531A is a valuable tool for general-purpose, low-power differential signal conditioning applications
