Digital to Analog D and A Convertor using R-2R Network
Product Code : JA-DEECP-1196
The Digital to Analog D and A Convertor using R-2R Network apparatus (SKU JA-DEECP-1196) shows how a resistor ladder of only two values, R and 2R, turns a binary input into a proportional analog voltage. Logic 1 and 0 are selected with an SPDT switch input, and the resulting voltage is read on a built-in voltmeter. Regulated supplies of 5 V and 15 V, each 150 mA, are fitted, and the circuit diagram is printed on the front panel with connections at sockets.
