TC7116/A/TC7117/A  
3-1/2 Digit Analog-to-Digital Converters with Hold  
Features:  
General Description:  
• Low Temperature Drift Internal Reference:  
- TC7116/TC7117 80 ppm/°C, Typ.  
- TC7116A/TC7117A 20 ppm/°C, Typ.  
• Display Hold Function  
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.  
• Directly Drives LCD or LED Display  
• Zero Reading with Zero Input  
• Low Noise for Stable Display:  
- 2V or 200mV Full Scale Range (FSR)  
• Auto-Zero Cycle Eliminates Need for Zero  
• Adjustment Potentiometer  
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.  
• True Polarity Indication for Precision Null  
Applications  
• Convenient 9V Battery Operation:  
(TC7116/TC7116A)  
• High-Impedance CMOS Differential Inputs: 1012Ω  
• Low-Power Operation: 10mW  
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 1012Ω input imped-  
ance. The 15μVP-P noise performance enables a “rock  
solid” reading. The auto-zero cycle ensures a zero  
display reading with a 0V input.  
Applications:  
• Thermometry  
• Bridge Readouts: Strain Gauges, Load Cells,  
Null Detectors  
• Digital Meters: Voltage/Current/Ohms/Power, pH  
• Digital Scales, Process Monitors  
• Portable Instrumentation  
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.
