DESCRIPTION
Dual and Quad, JFET Input
Precision High Speed Op Amps
The LT1057 is a matched JFET input dual op amp in
the industry standard 8-pin configuration, featuring a
combination of outstanding high speed and precision
specifications. It replaces all the popular bipolar and JFET
input dual op amps. In particular, the LT1057 upgrades the
performance of systems using the LF412A and OP-215
JFET input duals.
TheLT1058isthelowestoffsetquadJFETinputoperational
amplifier in the standard 14-pin configuration. It offers
significantaccuracyimprovementoverpresentlyavailable
JFET input quad operational amplifiers. The LT1058 can
replace four single precision JFET input op amps, while
saving board space, power dissipation and cost.
Both the LT1057 and LT1058 are available in the plastic
PDIP package and the surface mount SO package.
