A range of JFET input Op Amps from Analog Devices suitable for operation from single rail power supplies. The input common mode range of these operational amplifiers includes ground (or the negative supply rail with dual supplies) and most of the devices feature rail-to-rail outputs. Single, Dual and Quad package options are available.
Feature
- Single-supply operation- Output swings rail-to-rail- Input voltage range extends below ground- Single-supply capability from 3 V to 36 V
- High load drive- Capacitive load drive of 1000 pF, G = +1- Linear output current of 40mA, 0.5 V from supplies
- Excellent ac performance on 2.6 mA/amplifier- −3 dB bandwidth of 17 MHz, G = +1- 325 ns settling time to 0.01% (2 V step)- Slew rate of 30 V/µs
- Good dc performance- 700 µV maximum input offset voltage- 1 µV/°C offset voltage drift- 25 pA maximum input bias current
- Low distortion: −110 dBc worst harmonic at 20 kHz
- Low noise: 14 nV/√Hz at 10 kHz
- No phase inversion with inputs to the supply rails
Applications
- Battery-powered precision instrumentation
- hotodiode preamps
- Active filters
- 12-bit to 16-bit data acquisition systems
- Medical instrumentation
