Description

The Intersil ICL7139 and ICL7149 are high performance, low

power, auto-ranging digital multimeter lCs. Unlike other

autoranging multimeter ICs, the ICL7139 and ICL7149

always display the result of a conversion on the correct

range. There is no “range hunting” noticeable in the display.

The unit will autorange between the four different ranges. A

manual switch is used to select the 2 high group ranges. DC

current ranges are 4mA and 40mA in the low current group,

and 400mA and 4A in the high current group. Resistance

measurements are made on 4 ranges, which are divided into

two groups. The low resistance ranges are 4/40k . The high

resistance ranges are 0.4/4M . Resolution on the lowest

range is 1 .
