General Description

The TC7136 and TC7136A are low power, 3-1/2 digit

with liquid crystal display (LCD) drivers and analog-to-

digital converters. These devices incorporate an "inte-

grator output zero" phase, which enables over range

recovery.

The

performance

of

existing

TC7126,

TC7126A and ICL7126 based systems may be

upgraded with minor changes to external, passive

components.

The TC7136A has an improved internal zener refer-

ence voltage circuit which maintains the analog com-

mon temperature drift to 35ppm/°C (typical) and

75ppm/°C (maximum). This represents an improve-

ment of two to four times over similar 3-1/2 digit con-

verters.

The

costly,

space

consuming

external

reference source may be removed.

The TC7136 and TC7136A limit linearity error to less

than 1 count on 200mV or 2V full scale ranges. The roll-

over error (the difference in readings for equal magni-

tude, but opposite polarity input signals) is below ±1

count. High-impedance differential inputs offer 1pA

leakage currents and a 1012

Ω input impedance. The

differential reference input allows ratiometric measure-

ments for ohms or bridge transducer measurements.

The 15

µVP-P noise performance ensures a "rock solid"

reading. The auto-zero cycle enables a zero display

readout for a 0V input.
