DESCRIPTION
The LF353 are high speed JFET input dual oper-
ational amplifiers incorporating well matched, high
voltage JFET and bipolar transistors in a mono-
lithic integrated circuit.
The devices feature high slew rates, low input bias
and offset currents, and low offset voltage temper-
ature coefficient.
