AD22050 - Single-Supply Sensor Interface Amplifier

General Description

The AD22050 is a single-supply difference amplifier for amplifying and low-pass filtering small differential voltages (typically 100 mV FS at a gain of 40) from sources having a large commonmode voltage.

Supply voltages from +3.0 V to +36 V can be used.

Key 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 k ⍀ Drives 1 k ⍀ Load to +4 V Using V S = +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:.
