TC7116/A/TC7117/A

3-1/2 Digit Analog-to-Digital Converters with Hold

Features:

General Description:

• Low Temperature Drift Internal Reference:

- TC7116/TC7117 80 ppm/°C, Typ.

- TC7116A/TC7117A 20 ppm/°C, Typ.

• Display Hold Function

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.

• 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

• Adjustment Potentiometer

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_REF-) is not available, as it is with the

TC7106/7107. V_REF- is tied internally to analog

common in the TC7116A/7117A devices.

• True Polarity Indication for Precision Null

Applications

• Convenient 9V Battery Operation:

(TC7116/TC7116A)

• High-Impedance CMOS Differential Inputs: 10¹²

• Low-Power Operation: 10mW

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 input imped-

ance. The 15V_P-Pnoise performance enables a “rock

solid” reading. The auto-zero cycle ensures a zero

display reading with a 0V input.

Applications:

• Thermometry

• Bridge Readouts: Strain Gauges, Load Cells,

Null Detectors

• Digital Meters: Voltage/Current/Ohms/Power, pH

• Digital Scales, Process Monitors

• Portable Instrumentation

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.
