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.
