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. n The LT1058 is the lowest offset quad JFET input operational
amplifier in the standard 14-pin configuration. It offers
significant accuracy improvement over presently available
JFET input quad operational amplifiers. The LT1058 can
replace four single precision JFET input op amps, while
saving board space, power dissipation and cost. APPLICATIONS n n n n n Precision, High Speed Instrumentation
