General 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
