AD8684 - High Speed JFET Operational Amplifiers

Description

The AD8682 and AD8684 are dual and quad low power, precision (1 mV) JFET amplifiers featuring excellent speed at low supply currents.

The slew rate is typically 9 V/μs with a supply current under 250 μA per amplifier.

These unity-gain stable amplifiers have a typical gain bandwidth of 3.5 MHz.

Features

  • Low supply current: 250 μA/amp maximum High slew rate: 9 V/μs Bandwidth: 3.5 MHz typical Low offset voltage: 1 mV maximum @ 25°C Low input bias current: 20 pA maximum @ 25°C CMRR: 90 dB typical Fast settling time Unity-gain stable.
