The DEM-PCM1801 is a flexible evaluation board which supports the MCP4725 and MCP4726 digital to analog converters (DACs). It is mainly used for applications requiring low power consumption and for high accuracy analog to digital conversions (ADCs).

The DEM-PCM1801 is designed to be used as a general purpose evaluation board in areas such as motor control, digital audio processing, sensor signal conditioning, robotics, and more. The board supports standard SPI, I2C, interrupts, and ADC for controlling different peripheral devices.

The MCP4725 digital to analog converter (DAC) is an integrated circuit that integrates a host of components such as an operational amplifier, data latches, and an Adc. The MCP4725 works on a fixed voltage operation from Vss to Vcc+0.6V, with a quiescent current of 5 mA. It has a 12-bit input resolution with a ±10 mV accuracy. The DAC has two data ports which allow for both serial input/output (SIO) and parallel input/output (PIO).

The MCP4726 digital to analog converter (DAC) is an enhanced version of the MCP4725. It provides a higher resolution with a 16 bit input resolution and a ±16 mV accuracy. The DAC features two SIO/PIO ports for simultaneous conversion of serial and parallel inputs. The MCP4726 has a higher voltage range (1.75V to 5.25V) than the MCP4725, and consumes lower quiescent current (3 mA).

The DEM-PCM1801 evaluation board features a wide range of features. It can be used for applications requiring high accuracy ADCs, such as precision components identification, data entry of control codes, motor control, and signal transmission. The board includes an R/G/B LED indicator to simplify the process of comparing inputs and outputs, and a debug port for easy debugging. Moreover, the board offers the possibility to connect external components from the connection port.

The board also has the capability to measure the voltage, current, and temperature characteristics of the DACs. It features a very low-noise differential amplifier and a 16 bit 30 MSPS A/D converter. The board can also be used as a multichannel input device suitable for data acquisition, data monitoring, and signal processing.

In conclusion, the DEM-PCM1801 is a low power, high accuracy evaluation board for applications requiring both digital to analog and analog to digital conversions. It is suitable for a wide range of applications such as motor control, digital audio processing, sensor signal conditioning, and robotics. It can also be used for precision components identification and data entry tasks. The board supports a wide range of features such as R/G/B LED indicator, debug port, and connection port for external components. With its features and flexibility, the DEM-PCM1801 is the perfect solution for any application requiring a high accuracy ADC.
