Alterable from 40 to 1000 Output Span 20 mV to (VS – 0.25) V 1 Pole Low-Pass Filtering Available Offset Capability Differential Input Resistance 230 k Drives 1 k Load to +4 V Using VS = +5 V Supply Voltage: +3 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 Interface for Pressure Transducers, Position Indicator, Strain Gages and Other Low Level Signal Sources GENERAL DESCRIPTION The AD22055 accepts a differential signal from a bridge trans- ducer whose common-mode signal can be anywhere between the power supplies. One Technology Way, P.O. Box 9106, Norwood, MA 02062-9106, U.S.A. Tel: 617/329-4700 World Wide Web Site: http://www.analog.com Fax: 617/326-8703 © Analog Devices, Inc., 1997 The extended temperature range allows for local signal condi- tioning for oil and hydraulic pressure sensors as well as other automotive sensors. The use of an external gain resistor allows the user to compen- sate transducer gain error and temperature drift.
