General Description Features
The AZV831/AZV832 is single/dual channels Single Supply Voltage Range: 1.6V to 5.5V
rail-to-rail input and output amplifier, which provides Ultra-low Input Bias Current: 1pA (Typ.)
a wide input common-mode voltage range and output Offset Voltage: 0.5mV (Typ.), 2.5mV (Max.)
voltage swing capability for maximum signal swings Rail-to-Rail Input
in low supply voltage applications. The device is V : 300mV beyond Rails @ V =5V
CM CC
fully specified to operate from 1.6V to 5.0V single Rail-to-Rail Output Swing:
supply, or 0.8V and 2.5V dual supply applications. 10k Load: 4mV from Rail
It features very low supply current dissipation 70A 1k Load: 25mV from Rail
per channel, which is well suitable for today's Supply Current: 70A/Amplifier
low-voltage and/or portable systems. Unity Gain Stable
Gain Bandwidth Product: 1.0MHz
The AZV831/AZV832 features optimal performance Slew Rate: 0.45V/s @ V =5.0V
CC
in very low bias current of 1pA, which enables the IC Operation Ambient Temperature Range: -40C
to be used for integrators, photodiode amplifiers, and to 85C
piezoelectric sensors etc. The device has typical
0.5mV input offset voltage and provides 1MHz
bandwidth.
The AZV831/AZV832 adopts the latest packaging Applications
technology to meet the most demanding
space-constraint applications. The AZV831 is Sensors
available in standard SOT-23-5 and SC-70-5 Photodiode Amplification
packages. The AZV832 is offered in the traditional Battery-Powered Instrumentation
MSOP-8 and SOIC-8 packages. Pulse Blood Oximeter, Glucose Meter
