Digital-to-Analog Converters With Non-Volatile Memory and I2C™ From Microchip Feature 8-, 10- and 12-bit Resolution

Microchip Technology Inc., a leading provider of microcontroller, mixed-signal, analog and Flash-IP solutions, today announced the expansion of its non-volatile Digital-to-Analog Converter (DAC) product line with the MCP47FEBXX devices.  The low-power, single and dual-channel DACs feature 8-, 10- and 12-bit resolution, integrated EEPROM and an I2C™ interface, and are offered in 8-pin TSSOP packages.  The DACs are ideal for applications in the consumer and industrial markets, such as wireless microphones, mp3 player accessories and blood glucose test devices and applications such as motor control, instrumentation, sensor calibration, set point/offset trimming, among others.

The integrated EEPROM enables DAC settings to be recalled at power up, for added system flexibility.  The choice of 8-, 10- and 12-bit resolution provides flexibility with design requirements and cost.  The various shutdown modes significantly reduce the device current consumption for power critical applications.  These devices offer customers the ability to utilize the internal bandgap for device voltage reference, simplifying development and lowering system cost, or use an external voltage reference source in order to optimize their design.


“The MCP47FEBXX families of general-purpose DACs were designed to service a broadrange of markets and applications,” said Bryan J. Liddiard, marketing vice president of Microchip’s Analog and Interface Products Division.  “The integration and feature set offers customer system flexibility and power savings while simplifying their design efforts.  These devices are specified over a wide operating voltage range making them suitable in a variety of applications, including many portable, consumer and handheld devices.”
