Dual op-amp for battery-powered signal chains
The MAX492CSA+ is a dual general-purpose operational amplifier from Analog Devices in an 8-SOIC surface-mount package.
Bandwidth and drive for ADC front-ends
The 30 mA output drive per channel lets it swing into the sample-and-hold capacitor of a successive-approximation ADC without a separate buffer stage. Input offset voltage is trimmed to 200 µV typical, and input bias current runs 25 nA — low enough for most resistive-bridge and thermocouple circuits without a nulling trim pot.
