TC7106/A/TC7107/A

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

Features:

General Description:

• Internal Reference with Low Temperature Drift:

- TC7106/TC7107: 80 ppm/°C (Typical)

- TC7106A/TC7107A: 20 ppm/°C (Typical)

The TC7106A and TC7107A 3-1/2 digit direct display

drive Analog-to-Digital Converters allow existing

TC7106/TC7107 based systems to be upgraded. Each

device has a precision reference with a 20 ppm/°C

maximum temperature coefficient. This represents a 4

to 7 times improvement over similar 3-1/2 digit

converters. Existing TC7106 and TC7107 based

systems may be upgraded without changing external

passive component values. The TC7107A drives

common anode light emitting diode (LED) displays

directly with 8 mA per segment. A low cost, high

resolution indicating meter requires only a display, four

resistors, and four capacitors. The TC7106A low-power

drain and 9V battery operation make it suitable for por-

table applications.

• Drives LCD (TC7106) or LED (TC7107)

Display Directly

• Zero Reading with Zero Input

• Low Noise for Stable Display

• Auto-Zero Cycle Eliminates Need for Zero

Adjustment

• True Polarity Indication for Precision Null

Applications

• Convenient 9V Battery Operation (TC7106A)

• High-Impedance CMOS Differential Inputs: 10¹²Ω

• Differential Reference Inputs Simplify Ratiometric

Measurements

The TC7106A/TC7107A 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

• Low-Power Operation: 10 mW

offer 1 pA leakage current and

10¹²Ω input

Applications:

impedance. The differential reference input allows

ratiometric measurements for ohms or bridge

transducer measurements. The 15 µV_P–Pnoise

performance ensures a “rock solid” reading. The auto-

zero cycle ensures a zero display reading with a zero

volts input.

• Thermometry

• Bridge Readouts: Strain Gauges, Load Cells, Null

Detectors

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

• Digital Scales, Process Monitors

• Portable Instrumentation
