THS4531 Fully-Differential Op Amp



Texas Instruments' ultra-low power 0.25 mA, RRO, fully differential amplifier


Texas Instruments THS4531 Fully-Differential Op Amp Texas Instruments' THS4531 is a low-power, fully-differential op amp with input common-mode range below the negative rail and rail-to-rail output. The device is designed for low-power data acquisition systems and high density applications where power consumption and dissipation is critical.

The device features accurate output common-mode control that allows for dc coupling when driving analog-to-digital converters (ADCs). This control, coupled with the input common-mode range below the negative rail and rail-to-rail output, 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.
