8-, 10- and 12-bit DACs integrate EEPROM & I2C

Expanding its non-volatile DAC portfolio, Microchip has introduced the MCP47FEBXX low-power, single- and dual-channel DACs with 8-, 10- and 12-bit resolution. Integrating EEPROM and an I2C interface, the devices are suited for wireless microphones, MP3 player accessories, blood glucose test devices and applications such as motor control, instrumentation, sensor calibration and set point/offset trimming.

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 utilise the internal bandgap for device voltage reference, simplifying development and lowering system cost, or use an external voltage reference source in order to optimise their design.

The DACs are supported by Microchip’s 20-pin TSSOP and SSOP evaluation board (TSSOP20EV) priced at $9.99.

The MCP47FEBXX family is available now for sampling and volume production in 8-pin TSSOP packages.
