TC7106CPL [Microchip]

The TC7106 3½ digit LCD direct-display drive analog-to-digital converter has a reference with a 80ppm/°C max temperature coefficient. TC7106 based systems may be upgraded without changing external passive component values to the TC7106A for a more precise system. High impedance differential inputs offer 1pA leakage current and a 10¹² Ohm input impedance. The differential reference input allows ratiometric measurements for ohms or bridge transducer measurements. The 15µVp-p noise performance guarantees a great reading. The auto-zero cycle guarantees a zero display reading with a zero-volts input.
