Create A High Input Impedance, Rail-To-Rail Measurement System
Two very desirable features for a precision measurement system based on an analog-to-digital converter (ADC) are high input impedance and a wide input range, ideally including or extending slightly beyond the power-supply rails. The circuit described here does just that. Its very high input impedance is complemented by an input range that extends 300 mV beyond the supply rails. The example circuit uses a thermocouple and a resistance temperature detector (RTD) connected to...
