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
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).
