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 4/40kΩ. The high
resistance ranges are 0.4/4MΩ. Resolution on the lowest
range is 1Ω.
