LT1462CS8#PBF

LT1462CS8#PBF is a dual, 260µW C-Load picoampere bias current JFET input op-amp. It offers picoampere input bias currents (1pA typ) and unity gain stability for capacitive loads up to 10nF. The output can swing a 10K load to within 1.5V of either supply, just like op amps that require an order of magnitude more supply current. This unique combination of performance makes the LT1462 ideal over a wide range of input and output impedances. The input common mode range includes the positive rail. Typical applications include battery-powered systems, photocurrent amplifiers, low frequency, micropower active filters, low droop track-and-hold circuits.
