Description

The AS333Q is an automotive high precision operational amplifier designed with chopping stabilization technique which eliminates 1/f noise, and the cross over distortion presented in most RRIO amplifiers.

The AS333Q, RRIO amplifier (rail-to-rail input and output), provides not only maximum output voltage swing capability but also an extended 100mV common-mode voltage beyond the supply rail. The device is fully specified to operate from 1.8V to 5.5V single supply, or ±0.9V and ±2.5V dual supply applications.

The device features a good speed/power consumption ratio, offering 350kHz gain bandwidth while consuming only 17μA quiescent current. With the low input offset voltage 8μV and zero-drift offset voltage 0.02μV/°C, it is ideal for applications that require precision, especially for low power and high precision ones.

The AS333Q is available in SOT25 and SOT353 packages, and is AEC-qualified for automotive applications and temperature range grade 1, which is specified for operation from -40°C to +125°C among all supply voltages. The wide temperature ranges and high ESD tolerance facilitate their use in harsh applications.
