Image of Texas Instruments' THS4531/31A Fully-Differential Op Amps Texas Instruments' THS4531/31A are low-power, fully-differential op amps with an input common-mode range below the negative rail and rail-to-rail output. The devices is designed for low-power data acquisition systems and high density applications where power consumption and dissipation is critical.

The devices feature 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.
