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.
