LT1463 Dual/Quad Micropower, 260µW C-Load Picoampere Bias Current JFET Input Op Amps

The LT®1462 (dual) and LT1463 (quad) are the first micropower op amps (45µA max per amp) to offer 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/LT1463 ideal over a wide range of input and output impedances. In the design and testing of the LT1462/LT1463, particular emphasis has been placed on optimizing performance in the low cost SO-8 (dual) and 14-lead SO package (quad) for ±15V and ±5V supplies. The input common mode range includes the positive rail. Slew rate (0.08V/µs min) and gain bandwidth product (125kHz min) are 100% tested. A full set of matching specifications is also provided
