High-precision, dual-channel op amp provides accurate

signal conditioning in automotive ECUs.

compliant dual channel operational amplifier

(op amp). The device has an ultra-low input

offset voltage (8μV), and near zero-drift over

time and temperature for high-accuracy

signal conditioning in automotive ECUs.

This rail-to-rail input and output op amp

uses chopper stabilization to minimize input

offset voltage, reduce 1/f noise, and

decrease input crossover-distortion present

in most rail-to-rail input op amps.

Its low 12µA quiescent current, coupled with

a large open loop gain and common-mode

rejection (CMRR), make the AS2333Q

suitable for large amplification of very low-

level signals from sensors in a wide variety

of automotive applications.

The device’s rail-to-rail input has a common-

mode range of 100mV beyond the rails with

extremely low bias current. Its rail-to-rail

output swings within 50mV of the rails.

The AS2333Q is AEC grade 1 qualified with

an ambient temperature range of

-40ºC to +125ºC and is available in the

industry-standard SO-8 package.
