TC7117CPL by Microchip Technology

3-1/2 Digit A/D, w/ Hold
Features
Low Temperature Drift Internal Reference
80 ppm/u00b0C Typ.
Display Hold Function
Directly Drives LED Display
Guaranteed Zero Reading with Zero Input
Auto-Zero Cycle Eliminates Need for Zero Adjustment Potentiometer
True Polarity Indication for Precision Null Applications
High Impedance CMOS Differential Inputs: 1012 Ohm
Description
The TC7117 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 TC7117 drives common anode light emitting diode (LED) displays directly with an 8mA drive current per segment. 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.

Description
The TC7116A/TC7117A are 3-1/2 digit CMOS Analog- to-Digital Converters (ADCs) 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 TC7116A drives Liquid Crystal Displays (LCDs) and includes a back- plane driver. The TC7117A drives common anode Light Emitting Diode (LED) displays directly with an 8mA drive current per segment. These devices incorporate a display hold (HLDR) function. The displayed reading remains indefinitely, as long as HLDR is held high. Conversions continue, but output data display latches are not updated. The refer- ence low input (VREF-) is not available, as it is with the TC7106/7107. VREF- is tied internally to analog common in the TC7116A/7117A devices. The TC7116A/7117A reduces linearity error to less than 1 count. Rollover error (the difference in readings for equal magnitude but opposite polarity input signals) is below ±1 count. High-impedance differential inputs offer 1pA leakage current and a 1012  input imped- ance. The 15VP-P noise performance enables a “rock solid” reading. The auto-zero cycle ensures a zero display reading with a 0V input. The TC7116A and TC7117A feature a precision, low drift internal reference, and are functionally identical to the TC7116/TC7117. A low drift external reference is not normally required with the TC7116A/TC7117A.
