LT1464/LT1465

Dual/Quad Micropower,

1MHz C-Load Picoampere

Bias Current JFET Input Op Amps

FEATURES

DESCRIPTION

The LT

1464 (dual) and LT1465 (quad) are the first

micropower op amps (200µA 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 SO-8 (dual) and 14-lead SO (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.
