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 liq-  
uid crystal displays (LCDs) and includes a backplane  
driver. The TC7117A drives common anode light emit-  
ting 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) func-  
tion. The displayed reading remains indefinitely, as  
long as HLDR is held high. Conversions continue, but  
output data display latches are not updated. The refer-

Applications  
• Convenient 9V Battery Operation:

• High Impedance CMOS Differential Inputs: 1012Ω  
ence low input (V  
-) is not available, as it is with the  
REF  
TC7106/7107. V  
- is tied internally to analog com-  
REF  
mon in the TC7116A/7117A devices.  
• 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

ance. The 15µV  
noise performance enables a “rock  
P-P  
solid” reading. The auto-zero cycle ensures a zero dis-  
play reading with a 0V input.  
• 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.
