The MCP47FEB02A0-E/ST is a high performance, low power Digital to Analog (DAC) converter. This device combines a low-power, low-noise, low-voltage, 8-bit DAC with integrated reference, current buffered output, integrated power-on reset and an addressable interface. The MCP47FEB02A0-E/ST is suitable for applications requiring accurate data conversion, including audio applications and signal processing in consumer devices.

This device contains a low power 8-bit DAC with a buffered parallel current output. The reference output is typically offered to the user as a 10kHz voltage reference and a 10kHz current reference. The MCP47FEB02A0-E/ST provides a clean, high accuracy wide range of output currents and streamlines power supply design.

Application Fields of MCP47FEB02A0-E/ST

The MCP47FEB02A0-E/ST is designed to provide an accurate, low power and low noise solution to digital to analog conversion requirements. Its main applications include consumer audio products, including CD players and receivers, musical instruments and audio professional equipment, medical products, digital keypads, air conditioning systems and consumer electronics. Additionally, it is suitable for industrial, automotive and consumer applications which require digital-to-analog conversion.

Working Principle of the MCP47FEB02A0-E/ST

The MCP47FEB02A0-E/ST is based on the principle of "charge sharing" which is used to control DAC output current. Charge sharing allows for a higher DAC resolution and linearity than conventional resistive DACs. The device has a buffered parallel current output to drive an external load. This device also integrates an addressable interface, allowing access to three 8-bit DACs or one 24-bit DAC. This allows for individual DACs to be addressed or multiple DACs in series.

The device incorporates an automatic power-on reset circuit, allowing the device to automatically reset and power up when the supply voltage rises above its operating range. This feature is especially useful for applications with varying power supply voltages, such as those found in automotive applications. The MCP47FEB02A0-E/ST also incorporates an over-temperature protection circuit which will shut down the device if the ambient temperature rises above the specified limit.

The MCP47FEB02A0-E/ST utilizes a 10 kHz reference voltage/current to provide a low-noise, low-power voltage/current buffer. This reference voltage/current is adjustable with an external capacitor, allowing for the ability to accurately adjust and maintain the desired output voltage/current. The device also has additional features such as an integrated power-on reset, an addressable interface, a low-noise, low-power 8-bit DAC, and a buffered parallel current output.

The MCP47FEB02A0-E/ST provides a unique solution for digital-to-analog conversion applications. Its low-power, low-noise, integrated power-on reset, over-temperature protection and addressable interface provide a reliable and accurate solution for audio, medical, automotive and other applications.
