ADI LT1465CN#PBF

The LT1464 (dual) and LT1465 (quad) are the first micropower op amps (200uA max per amp) to offer picoampere input bias currents (500fA 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 LT1464/LT1465 ideal over a wide range of input and output impedances. In the design and testing of the LT1464/LT1465, particular emphasis has been placed on optimizing performance in the low cost S0-8 (dual) and 14-lead S0 (quad) package for ±15V and ±5V supplies. The input common mode range includes the positive rail. Slew rate (0.5V/μs min) and gain bandwidth product (650kHz min) are 100% tested. A full set of matching specifications is also provided.
