LF253, LF353
Wide bandwidth dual JFET operational amplifiers
Features
■ Low power consumption
■ Wide common-mode (up to V_CC+) and
differential voltage range
■ Low input bias and offset current
■ Output short-circuit protection
■ High input impedance JFET input stage
■ Internal frequency compensation
■ Latch up free operation
■ High slew rate 16 V/µs (typical)
Description
These circuits are high speed JFET input dual
operational amplifiers incorporating well matched,
high voltage JFET and bipolar transistors in a
monolithic integrated circuit.
The devices feature high slew rates, low input
bias and offset currents, and low offset voltage
temperature coefficient.
