Here is the description about TC7116/TC7116A/TC7117/A of the 3-1/2 Digit Analog-to-Digital Converters with Hold. 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. 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.
Here are the features: Low Temperature Drift Internal Reference: - TC7116/TC7117 80 ppm/°C, Typ and - TC7116A/TC7117A 20 ppm/°C, Typ; Display Hold Function; 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; True Polarity Indication for Precision Null Applications; High-Impedance CMOS Differential Inputs: 1012; Low-Power Operation: 10mW.
Here are its maximum ratings. Supply Voltage: TC7116/TC7116A (V+ to V-) is 15V. TC7117/TC7117A (V+ to GND) is +6V. V- to GND is -9V. Reference Input Voltage (Either Input) is V+ to V-. Operating Temperature: C (Commercial) Device is from 0°C to +70°C and I (Commercial) Device is from 0°C to +70°C. Storage Temperature is from -65°C to +150°C.
