GENERAL DESCRIPTION
The AD22057 is a single-supply difference amplifier for ampli-
fying and low-pass filtering small differential voltages (typically
100 mV FS at a gain of 40) from sources having a large common-
mode voltage.
Supply voltages from +3.0 V to +36 V can be used. The input
common-mode range extends from below ground to +24 V using
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 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
APPLICATIONS
Current Sensing
Motor Control
Interface for Pressure Transducers, Position Indicators,
Strain Gages, and Other Low Level Signal Sources
Accelerometers
a +5 V supply with excellent rejection of this common-mode
voltage. This is achieved by the use of a special resistive attenua-
tor at the input, laser trimmed to a very high differential balance.
Provisions are included for optional low-pass filtering and gain
adjustment. An accurate midscale offset feature allows bipolar
signals to be amplified.
