3 Description

The OPA391 and OPA2391 (OPAx391) feature a

unique combination of high bandwidth (1 MHz)

along with very-low quiescent current (24 μA) in

high-precision amplifiers. These features combined

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

an exceptional choice in high-gain, low-power

applications. Ultra-low input bias current of 10 fA,

only 45 μV of offset (maximum), and 1.2 μV/°C of

drift over temperature help maintain high precision in

ratiometric and amperometric sensor front ends that

have demanding low-power requirements.

The OPAx391 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.
