3 Description
The LF356-MIL device are the first monolithic JFET
input operational amplifiers to incorporate well-
matched, high-voltage JFETs on the same chip with
standard bipolar transistors (BI-FET™ Technology).
These amplifiers feature low input bias and offset
currents/low offset voltage and offset voltage drift,
coupled with offset adjust, which does not degrade
drift or common-mode rejection. The devices are also
designed for high slew rate, wide bandwidth,
extremely fast settling time, low voltage and current
noise and a low 1/f noise corner.
