AD8203

Data Sheet High Common-Mode Voltage, Single-Supply Difference Amplifier AD8203 FEATURES High common-mode voltage range −6 V to +30 V at a 5 V supply voltage Operating temperature range: −40°C to +125°C Supply voltage range: 3.5 V to 12 V Low-pass filter (1-pole or 2-pole) Excellent ac and dc performance ±1 mV voltage offset (8-lead SOIC) ±1 ppm/°C typical gain drift 80 dB CMRR minimum dc to 10 kHz APPLICATIONS Transmission control Diesel injection control Engine management Adaptive suspension control Vehicle dynamics control GENERAL DESCRIPTION The AD8203 is a single-supply difference amplifier for amplifying and low-pass filtering small differential voltages in the presence of a large common-mode voltage (CMV). The input CMV range extends from −6 V to +30 V at a typical supply voltage of 5 V. The AD8203 is available in packaged form. The MSOP and SOIC packages are specified over a wide temperature range, from −40°C to +125°C, making the AD8203 well-suited for use in m...
