DACs with non-volatile memory

25 February 2015 Analogue, Mixed Signal, LSI

Microchip announced the expansion of its non-volatile digital-to-analog converter (DAC) product line with the MCP47FEBXX. These 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 chips are ideal for applications in the consumer and industrial markets, such as wireless microphones, MP3 player accessories and blood glucose test devices; and motor control, instrumentation, sensor calibration, setpoint/offset trimming, among others.

The integrated EEPROM enables DAC settings to be recalled at power-up, for added system flexibility. 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.
