Digital-to-analogue converters with non-volatile memory and I2C interface

Microchip has announced the expansion of its non-volatile digital-to-analogue converter (DAC) product line with the MCP47FEBXX Series. 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 and others, says the company. 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 MCP47FEBXX series is supported by Microchip's 20-Pin TSSOP and SSOP evaluation board (TSSOP20EV).
