The LT1457 is a dual, JFET input op amp optimized for
handling large capacitive loads in combination with preci-
sion performance.
Precision specifications include 220
V offset voltage in
plastic and surface mount packages. At 70
°C input bias
current is 50pA, input offset current is 20pA. Channel
separation is 130dB.
Other dual JFET input op amps from Linear Technology
include the LT1057, which is three times faster than the
LT1457 but at the expense of significantly lower capacitive
load handling capability; and the LT1113 with 4.5nV/
√Hz
voltage noise.
