General Description
The AZV831/AZV832 is single/dual channels
rail-to-rail input and output amplifier, which provides
a wide input common-mode voltage range and output
voltage swing capability for maximum signal swings
in low supply voltage applications. The device is
fully specified to operate from 1.6V to 5.0V single
supply, or ±0.8V and ±2.5V dual supply applications.
It features very low supply current dissipation 70µA
per channel, which is well suitable for today's
low-voltage and/or portable systems.
The AZV831/AZV832 features optimal performance
in very low bias current of 1pA, which enables the IC
to be used for integrators, photodiode amplifiers, and
piezoelectric sensors etc. The device has typical
0.5mV input offset voltage and provides 1MHz
bandwidth.
The AZV831/AZV832 adopts the latest packaging
technology to meet the most demanding
space-constraint applications. The AZV831 is
available in standard SOT-23-5 and SC-70-5
packages. The AZV832 is offered in the traditional
MSOP-8 and SOIC-8 packages.
