GENERAL DESCRIPTION

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 opera-

tion 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/√Hz voltage noise

density, recommends them for battery-powered audio applica-

tions. Capacitive loads to 200 pF are handled without oscillation.

The OP196/OP296/OP496 are specified over the

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-lead

OP196/OP296/OP496 The OP196 family of operational amplifiers is comprised of singlesupply, micropower, rail-to-rail input and output amplifiers. Input offset voltage (VOS) is only 300 µV maximum, while the output will deliver ±5 mA to a load. Supply current is only 50 µA, while bandwidth is over 450 kHz and slew rate is 0.3 V/µs. TPC 36 is a simplified schematic of the OP196—it displays the novel circuit design techniques used to achieve this performance. the supply rails.

OP196/OP296/OP496 same potential and no current flows in R1. Since there is no current flow in R1, the same condition must exist in R2; thus, the output of the circuit tracks the input signal. When the input signal is below 0 V, the output voltage of A1 is forced to 0 V. This condition now forces A2 to operate as an inverting voltage follower because the noninverting terminal of A2 is also at 0 V. The output voltage of VOUTA is then a full-wave rectified version of the input signal.
