General Description:
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.
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 (V

common in the TC7116A/7117A devices.
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 10
ance. The 15μV
solid” reading. The auto-zero cycle ensures a zero
display reading with a 0V input.
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.
