LT1057/LT1058
Dual and Quad, JFET Input
Precision High Speed Op Amps
FEATURES DESCRIPTION
n
14V/s Slew Rate: 10V/s Min
The LT 1057 is a matched JFET input dual op amp in
n
5MHz Gain-Bandwidth Product
the industry standard 8-pin configuration, featuring a
n
Fast Settling Time: 1.3s to 0.02%
combination of outstanding high speed and precision
n
150V Offset Voltage (LT1057): 450V Max
specifications. It replaces all the popular bipolar and JFET
n
180V Offset Voltage (LT1058): 600V Max
input dual op amps. In particular, the LT1057 upgrades the
n
2V/C V Drift: 7V/C Max
performance of systems using the LF412A and OP-215
OS
n
50pA Bias Current at 70C
JFET input duals.
n
Low Voltage Noise:
The LT1058 is the lowest offset quad JFET input operational
13nV/Hz at 1kHz
amplifier in the standard 14-pin configuration. It offers
26nV/Hz at 10Hz
significant accuracy improvement over presently available
JFET input quad operational amplifiers. The LT1058 can
replace four single precision JFET input op amps, while
APPLICATIONS
saving board space, power dissipation and cost.
