THS4531A www.ti.com SLOS823A – DECEMBER 2012 – REVISED JANUARY 2013 Ultra Low Power, Rail-to-Rail Output, Fully-Differential Amplifier Check for Samples: THS4531A 1 FEATURES Ultra Low Power: – Voltage: 2.5 V to 5.5 V – Current: 250 A – Power-Down Mode: 0.5 A (typ) Fully-Differential Architecture Bandwidth: 36 MHz Slew Rate: 200 V/s THD: –120 dBc at 1 kHz (1 VRMS, RL= 2 k) Input Voltage Noise: 10 nV/√Hz (f = 1 kHz) High DC Accuracy: – VOS: ±100 V – VOS Drift: ±3 V/C (–40°C to +125°C) – AOL: 114 dB Rail-to-Rail Output (RRO) Negative Rail Input (NRI) Output Common-Mode Control DESCRIPTION The THS4531A 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. The THS4531A is also a valuable tool for general-purpose, low-power differential signal conditioning applications. The THS4531A is characterized for operation over the extended industrial temper……
