General Description

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

drive analog-to-digital converters allow existing 7106/

7107 based systems to be upgraded. Each device has

a precision reference with a 20ppm/°C max tempera-

ture coefficient. This represents a 4 to 7 times improve-

ment over similar 3-1/2 digit converters. Existing 7106

and 7107 based systems may be upgraded without

changing external passive component values. The

TC7107A drives common anode light emitting diode

(LED) displays directly with 8mA 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 portable 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 1pA leakage current and a 1012

Ω input imped-

ance. The differential reference input allows ratiometric

measurements for ohms or bridge transducer mea-

surements. 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.
