3 Description

The OPA396, OPA2396, and OPA4396 (OPAx396)

feature a combination of high bandwidth (1MHz) along

with very low quiescent current (23.5μA) in a highprecision

amplifier. These features combined with

rail-to-rail input and output make these devices an

excellent choice in high-gain, low-power applications.

An ultra-low input bias current of 10fA, 100μV of offset

(maximum), and 1.2μV/°C of drift over temperature

help maintain high precision in ratiometric and

amperometric sensor front ends that have demanding

low-power requirements.

The OPAx396 use Texas Instrument's proprietary

e‑trim™ operational amplifier technology, enabling a

unique combination of ultra-low offset and low input

offset drift without the need for any input switching or

auto-zero techniques. The CMOS-based technology

platform also features a modern, robust output stage

design that is tolerant of high output capacitance,

alleviating stability problems that are common in

typical low-power amplifiers.
