The OP196 family of CBCMOS operational amplifiers features micropower
operation and rail-to-rail input and output ranges.
The extremely low power requirements and guaranteed operation from +3 V to
+12 V make these amplifiers perfectly suited to monitor battery usage and
to control battery charging. Their dynamic performance, including 26
nV/(root)Hz voltage noise density, recommends them for battery-powered
audio applications. Capacitive loads to 200 pF are handled without
oscillation.
The OP196/OP296/OP496 are specified over the HOT extended industrial (-40°C
to +125°C) temperature range. +3 V operation is specified over the 0°C to
+125°C temperature range. The single OP196 and the dual OP296 are available
in 8-pin plastic DIP and SO-8 surface mount packages. The quad OP496 is
available in 14-pin plastic DIP and narrow SO-14 surface mount packages.
Check factory for availability of the OP296 and OP496 in the TSSOP package.
