AS2333 1.8V, MICROPOWER CMOS ZERO-DRIFT OPERATIONAL AMPLIFIERS Description Pin Assignments The AS2333 is dual CMOS operational amplifier designed with (Top View) chopping stabilization technique. This product can provide ultra-low input offset voltage (8V 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. SO-8/MSOP-8 The device is optimized for low voltage single supply application, (Top View) especially for low-power high-precision applications. OUTA 1 8 V+ The AS2333 is available in the standard 8-pin SO-8, MSOP-8, and U- Exposed OUTB -INA 2 7 Thermal DFN3030-8 (Type E) packages, and is specified for operation from +INA 3 6 -INB Pad -40C to +125C.
