SC7001Q
33/4 DIGITS LCD DISPLAY ,3260-COUNT A/D FOR DMM
DESCRIPTION
The SC7001Q is a low power CMOS dual-slope A/D converter with 3
3/4-digit numeric and 33-segment bar-graph LCD display driver, auto-
ranging, and single 3V battery operation.
It is ideal for high performance auto-range DMM applications with
3260 counts full-scale.
The SC7001Q provides many user function: Manual Range Hold/Data
Hold/Auto Power-off/Voltage/Current/Resistance measurement/Diode
Test/Continuity Check(Beeper). The built-in high temperature-stable CMOS
QFP-80-14×20-0.8
bandgap reference and a CMOS Op Amp for ac-to-dc conversion are
economical of saving external components. In addition, the voltage doubler
enables a high performance digital multimer to be built with single 3V power
supply operation.
