The analog subsystem consists of an analog-to-digital converter (ADC) and a programmable gain amplifier (PGA) with a wide gain range from 2.94V/V to 971.10V/V. To minimize power supply noise, the bridge sensor is biased with an internal 4V voltage regulator. The ADA4558 is fully specified from −40°C to +150°C. The device operates from battery supply voltages of 6V to 18V. The ADA4558 is available in a 4mm×4mm, 20-lead lead frame chip scale package (LFCSP).
