Description

The ADA4558 is a fully integrated, sensor signal conditioner IC for bridge sensors. The device provides digital nonlinearity correction and temperature compensation via internal or external sensed temperatures using on-chip correction and calibration hardware that can be optimized for a specific bridge sensor.?The ADA4558 utilizes a fourth-order digital correction algorithm and delivers a system accuracy of 0.1% full scale range (FSR) for bridge sensors with second-order nonlinearity sensitivity. The ADA4558 includes a local interconnect network (LIN) physical interface for single-wire, high voltage communications in automotive environments. LIN 2.1 and earlier versions are supported. The LIN interface allows access to measurements, end of line (EOL) calibration, and a wide range of diagnostic functions.?The analog subsystem consists of an analog-to-digital converter (ADC) and a programmable gain amplifier (PGA) with a wide gain range from 2.94 V/V to 971.10 V/V. To minimize power supply noise, the bridge sensor is biased with an internal 4 V voltage regulator. The ADA4558 is fully specified from ?40?C to +150?C. The device operates from battery supply voltages of 6 V to 18 V. The ADA4558 is available in a 4 mm ? 4 mm, 20-lead lead frame chip scale package (LFCSP).?Applications Strain gage Pressure signal conditioner for automotive vehicles?
