Diodes Incorporated AS333x Micropower CMOS Op Amplifiers

Diodes Incorporated AS333x Micropower CMOS Operational Amplifiers implement a chopping stabilization technique. The design eliminates 1/f noise and cross-over distortion in most RRIO amplifiers. The AS333x RRIO amplifier (rail-to-rail input and output) features maximum output voltage swing capability and an extended 100mV common-mode voltage beyond the supply rail. The devices are fully specified to operate from 1.6V to 5.0V single supply or ±0.8V and ±2.5V dual supply applications.

The Diodes Incorporated AS333x micropower CMOS operational amplifiers offer a good speed/power consumption ratio with 350kHz gain bandwidth while consuming only 17μA quiescent current. Utilizing the low input offset voltage of 8μV and zero-drift offset voltage of 0.02μV/°C, the device is ideal for applications requiring precision, especially for low and high precision.

The AS333 is housed in SOT25 and SOT353 packages and 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.
