The R2R DAC Board is a DAC module based 8-bit Digital to Analog Converter that provides a perfect way for converting a digital voltage signal into analog. This performance driven additional board supports high quality 8-bit resolution. Making use of the R/2R resistor network, the board facilitates conversion of an 8-bit value from the microcontroller port into an equivalent analog voltage.

While the R2R DAC Board requires 2N resistors for successful execution of the N-bit conversion process, it actually makes use of only two resistor values. The resistor values are in the ratio of 1:2. The R2R DAC additional board has been provided with a 2x5 connector CN1 through which it gets connected to a development system. The connection gets completed via one of the 2x5 connectors provided on the development system itself. The analog voltage signal gets delivered via a screw terminal CN2.

The R/2R ladder DAC comes equipped with MCP6284 operational amplifier. This amplifier is used as a buffer in order to drive loads with current consumption of up to 20mA. Additionally, it also supports rail-to-rail input and output swing, with a common mode input voltage range of VDD + 300mV to VSS.
