Device Selection Table

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 (VREF-) is not available, as it is with the

TC7106/7107. VREF- is tied internally to analog

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 1012

Ω input imped-

ance. The 15

μVP-P noise performance enables a “rock

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.
