AS2333

1.8V, MICROPOWER

CMOS ZERO-DRIFT OPERATIONAL AMPLIFIERS

Description

The AS2333 is dual CMOS operational amplifier designed with

chopping stabilization technique. This product can provide ultra-low

input offset voltage (8μV typical) and near zero-drift over time and

temperature. This technique also eliminates 1/f noise and the cross-

over distortion present in most rail-to-rail input operational amplifiers.

The high-precision, low quiescent current amplifier offers high-

impedance inputs that have a common-mode range 100mV beyond

the rails, and a rail-to-rail output that swings within 50mV of the rails.

Single or dual supplies as low as 1.8V (±0.9V) and up to 5.5V

(±2.75V) can be used.

The device is optimized for low voltage single supply application,

especially for low-power high-precision applications.

The AS2333 is available in the standard 8-pin SO-8, MSOP-8, and U-

DFN3030-8 (Type E) packages, and is specified for operation from

-40°C to +125°C.
