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?.
