TC7117CKW (Microchip) is a 3-1/2 digit CMOS analog-to-digital converter from the TC7116/TC7117 family, with seven-segment decoders, reference and clock on chip, in a 44-pin PQFP package.

• 0.05% resolution · 2 V or 200 mV full-scale range · display hold function (HLDR)
• Low-drift internal reference (80 ppm/°C typ. for the TC7117) · true polarity indication · zero reading with zero input
• High-impedance CMOS differential inputs (10¹² Ω) · 10 mW low-power operation
• Auto-zero cycle eliminates the zero-adjustment potentiometer · 0 °C to +70 °C temperature range (44-pin PQFP)
