* 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
* True Polarity Indication for Precision Null
Applications
* Convenient 9V Battery OperationTC7116/TC7116A)
* High Impedance CMOS Differential Inputs: 1012§Ů
* Low Power Operation: 10mW
Applications* Thermometry
* Bridge Readouts: Strain Gauges, Load Cells,Null Detectors
* Digital Meters: Voltage/Current/Ohms/Power, pH
* Digital Scales, Process Monitors
* Portable Instrumentation
General Description
The TC7116A/TC7117A are 3-1/2 digit CMOS analogto-digital
converter(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 backplane driver. The TC7117A drives
common anode light emitting diode (LED) displays directly with an 8mA
drive current per segment.
