New High Precision Op-Amp AS2333



The AS2333 is dual CMOS operational amplifiers 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 presented 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 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.


  • Meets 2.5V,3,3V,5V popular power supply domain for portable application
  • Minimizes errors associated with input offset voltage.
  • Provides high precision signal chain
  • Low power consumption for portable application
