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 crossover distortion present in most rail-to-rail input operational amplifiers. The high-precision, low quiescent current amplifier offers highimpedance 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.
