Microchip Technology’s non-volatile digital-to-analogue converter (DAC) product line gains the MCP47FEBXX series of 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.

Microchip Technology’s non-volatile digital-to-analogue converter (DAC) product line gains the MCP47FEBXX series of 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 suitable for applications in the consumer and industrial markets; 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 reduce the device current consumption for power critical applications. These devices offer designers the ability to use the internal bandgap for device voltage reference, simplifying development and lowering system cost, or use an external voltage reference source.

“The MCP47FEBXX families of general-purpose DACs were designed to service a broad range 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.”

The MCP47FEBXX is supported by Microchip’s 20-Pin TSSOP and SSOP Evaluation Board (Part # TSSOP20EV, $9.99).

The MCP47FEBXX is available in 8-pinTSSOP packages, at prices ranging from $0.60 to $1.78 (5000).
