DESCRIPTION
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.
