Diodes Incorporated AS333Qx Automotive Micropower CMOS Operational Amplifiers are automotive, high-precision amps designed with a chopping stabilization technique. This technique eliminates 1/f noise and the cross-over distortion of most rail-to-rail input and output (RRIO) amplifiers. The AS333Qx RRIO amps (rail-to-rail input and output) supply maximum output voltage swing capability and an extended 100mV common-mode voltage beyond the supply rail. The amps are fully specified to operate from 1.6V to 5.0V single supply or ±0.8V 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 of 8μV and zero-drift offset voltage of 0.02μV/°C, it is ideal for applications that require precision, especially for low-power and high-precision ones.
The Diodes Incorporated AS333Qx is AEC-qualified and designed for automotive applications. The devices feature a grade 1 temperature range, specified for operation from -40°C to +125°C among all supply voltages. The wide temperature ranges and high ESD tolerance facilitate use in harsh applications.
