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 |
Description 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.
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 |
