DESCRIPTION
®
The LT
1057 is a matched JFET input dual op amp in
the industry standard 8-pin confi guration, featuring a
combination of outstanding high speed and precision
specifi cations. 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.
The LT1058 is the lowest offset quad JFET input operational
amplifi er in the standard 14-pin confi guration. It offers
signifi cant accuracy improvement over presently available
JFET input quad operational amplifi ers. 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.
