These 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.

Features

Advantages

Replace expensive hybrid and module FET op amps
Rugged JFETs allow blow-out free handling compared with MOSFET input devices
Excellent for low noise applications using either high or low source impedance-very low 1/f corner
Offset adjust does not degrade drift or common-mode rejection as in most monolithic amplifiers
New output stage allows use of large capacitive loads (5,000 pF) without stability problems
Internal compensation and large differential input voltage capability

Applications

Precision high speed integrators
Fast D/A and A/D converters
High impedance buffers
Wideband, low noise, low drift amplifiers
Logarithmic amplifiers
Photocell amplifiers
Sample and Hold circuits
