R2R DAC Board

R2R DAC Board

Our Price: $15.16


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

IC/Module: MCP6284 Rail-to-Rail Operational Amplifier

Designed with Microchip’s advanced CMOS process, the MCP6284 operational amplifier can operate from a single supply voltage as low as 2.2 V, while drawing just 450 µA (typical) quiescent current. This Op Amp features a Chip Select (CS) input for dual op amps in an 8-pin package. It has Common Mode Rejection Ratio of 65 dB (typical) and provides wide bandwidth for the current.

Operating Voltage

The R2R DAC Board is usable with both 5V and 3.3V systems. As such, it smartly operates on a wide range of power supply, from 3.3V to 5V.


The R2R DAC Board is an ideal cost-effective solution for applications that require low-resolution digital to analog converters. This low power consuming, flexible solution is perfect for all MCU architectures.
