TC7116

The TC7116 is a 3½ digit CMOS analog-to-digital converter (ADC) containing all the active components necessary to construct a 0.05% resolution measurement system. Seven-segment decoders, polarity and digit drivers, voltage reference, and clock circuit are integrated on-chip. The TC7116 drives liquid crystal displays (LCDs) and includes a backplane driver. These devices incorporate a display hold (HLDR) function. Roll-over error (the difference in readings for equal magnitude but opposite polarity input signals) is below ±1 count. High-impedance differential inputs offer 1 pA leakage current and a 1012 Ohm input impedance. The auto-zero cycle guarantees a zero display reading with a 0V input.
