Data Acquisition - Digital to Analog Converters (DAC) enable the conversion of digital signals into analog signals. MCP4811-E/MC is a type of DAC which is a low power, single channel, 12-bit voltage output Digital to Analog Converter. It is a CMOS device with SPI compatible serial interface and a +5V operating voltage.

Features and Benefits

MCP4811-E/MC features and benefits include its low power consumption, minimal external components required to operate and a wide supply voltage range from 2.7V to 5.5V. This makes the device suitable for many applications. It also has a data latched architecture which allows data to be written to internal registers without any danger of corruption. Data is written via the Serial Peripheral Interface (SPI) from the host processor. A power-on reset circuit provides the user with an initial DAC output of zero volts.

Applications

MCP4811-E/MC is suitable for a number of applications including adjustable power supply, precision current monitoring, pulse width modulation and signal generation. For example, in adjustable power supplies, it can be used to add fine tuning to the output voltage. The 12-bit DAC allows for a resolution of 1mV and a 0.5% initial accuracy. Furthermore, the device can be used in precision current monitoring systems to set a desired set and monitor the current. In pulse width modulation it can be used to calibrate signal conditioning filters to generate various signal types.

Working Principle

When data is received from the host processor, it is written to the DAC’s internal register, which stores the most recently written value. The DAC then performs a Digital to Analog conversion on the data in the register, resulting in an analog voltage output. The voltage range of the output is from 0V to 4.095V, with a 12-Bit accuracy of 1mV. This voltage is fed to the DAC output pin, and is accessible for external components to use for further signal processing.

Conclusion

MCP4811-E/MC is an effective and efficient Digital to Analog Converter with many applications. It is a low power device with wide voltage range and minimal external components required to operate. It has a data latched architecture which allows data to be written to internal registers without the danger of corruption and a power-on reset circuit which provides the user with a DC output of zero volts. Its working principle consists of the DAC performing an internal Digital to Analog conversion on data stored in the DAC\'s internal register, which leads to an analog voltage range from 0V to 4.095V.
