ADA4558WHCPZ-RL

Overview

The ADA4558WHCPZ-RL is a bridge sensor signal conditioner IC featuring a LIN interface, nonlinearity correction, and temperature compensation. It operates on a 6 V to 18 V supply with an operating current of 8.2 mA across the -40°C to +150°C range. The device includes a programmable gain amplifier (PGA) with a gain range from 2.94 V/V to 971.10 V/V and a 14-bit ADC. System accuracy reaches 0.1% FSR over temperature. It utilizes EEPROM for calibration data storage and provides fault protection for open circuits and short circuits within a 20-lead LFCSP package.
