• Portable Instrumentation

General Description:

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.

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

offer 1 pA leakage current and a 1012

Ω input

impedance. The differential reference input allows

ratiometric

measurements

for

ohms

or

bridge

transducer

measurements.

The

15 µVP–P noise

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

zero cycle ensures a zero display reading with a zero

volts input.
