AS333Q
1.8V, MICROPOWER
CMOS ZERO-DRIFT OPERATIONAL AMPLIFIERS
Description
Pin Assignments
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, an 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.
SOT25
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 the SOT25 package 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 its use in harsh applications.
