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.
