Autoranging Multimeter  
Features  
Description  
• 13 Ranges - ICL7139  
- 4 DC Voltage 400mV, 4V, 40V, 400V  
- 1 AC Voltage 400V  
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.
