AD22057:  Single Supply Sensor Interface Amplifier

Product Description

The AD22057 is a single-supply difference amplifier for the amplification and low-pass filtering of small differential voltages from sources having a large common-mode voltage.

Supply voltages from +3 V to +36 V can be used. The input common-mode range extends from below ground to 24 V using a +5 V supply with excellent rejection of this common-mode voltage.

This range is achieved by the use of a special resitive attenuator at the input, laser trimmed to a very high differential balance. Low initial offset voltage and offset voltage drift are specified, and long-term stability of gain and offset voltage is also provided.

Provisions are included for optional low-pass filtering and gain adjustment. An accurate midscale offset feature allows bipolar signals to be amplified.

Features

  • Gain of ×20 Alterable from ×1 to ×160
  • Input CMR from Below Ground to 6× (VS - 1 V)
  • Output Span 20 mV to (VS - 0.2) V
  • 1-, 2-, 3-Pole Low-Pass Filtering Available
  • Accurate Midscale Offset Capability
  • Differential Input Resistance 400 kΩ
  • Drives 1kΩ Load to +4 V Using VS = +5 V
  • Supply Voltage: +3.0 V to +36 V
  • Transient Spike Protection and RFI
    Filters Included
  • Peak Input Voltage (40 ms): 60 V
  • Reversed Supply Protection: -34 V
  • Operating Temperature Range: -40°C
    to +125°C
