SLOS823A –DECEMBER 2012–REVISED JANUARY 2013

Ultra Low Power, Rail-to-Rail Output, Fully-Differential Amplifier

Check for Samples: THS4531A

FEATURES

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.

•

Ultra Low Power:

–

Voltage: 2.5 V to 5.5 V

Current: 250 µA

Power-Down Mode: 0.5 µA (typ)

•

Fully-Differential Architecture

Bandwidth: 36 MHz

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.

Slew Rate: 200 V/µs

THD: –120 dBc at 1 kHz (1 V_RMS, R_L= 2 kΩ)

Input Voltage Noise: 10 nV/√Hz (f = 1 kHz)

High DC Accuracy:

–

V_OS: ±100 µV

V_OSDrift: ±3 µV/˚C (–40°C to +125°C)

A_OL: 114 dB

•

Rail-to-Rail Output (RRO)

Negative Rail Input (NRI)

Output Common-Mode Control

The THS4531A is characterized for operation over

the extended industrial temperature range from

–40°C to +125°C. The following package options are

available:
