Microchip Introduces Industry’s First Quad Digital-to-Analogue Converter

17 SEPTEMBER 2009

Microchip announces the MCP4728 Digital-to-Analogue Converter (DAC) – the industry’s first 12bit Quad DAC to include non-volatile EEPROM, enabling the DAC’s configuration to be loaded automatically during power-up. The on-board EEPROM, coupled with an internal voltage reference, four-channel architecture and rail-to-rail precision output amplifier, enables the MCP4728 DAC to significantly reduce the size and component cost in a variety of battery powered and power-constrained applications. Through the integrated I2CTM serial interface, designers can configure the MCP4728 DAC’s input codes, configuration bits and I2C address bits. This configuration information is stored in the non-volatile EEPROM and therefore retained after power is removed, making it available immediately after power is reapplied and reconfiguring the DAC during power-up. The MCP4728 Evaluation Board (Part # MCP4728EV, $15) is available to help designers quickly evaluate the MCP4728 DAC in their applications. The MCP4728 DAC is sampling now and is available in a 10-pin MSOP package.
