DACs with NVM retain settings in power-off
The six-member MCP48FEBXX DAC family offers integrated EEPROM to save DAC settings at power-down, while the MCP48FVBXX family provides lower-cost alternatives for applications that do not require integrated memory. These low-power, single and dual-channel DACs feature 8-, 10- and 12-bit resolution, a Serial Peripheral Interface (SPI), and are available in 10-pin MSOP packages. Examples of their wide range of applications in the consumer, industrial, automotive and other markets, includes set-point/offset trimming, sensor calibration, instrumentation, and motor control.
The integrated EEPROM option enables DAC settings to be restored at power-up and reduces microcontroller overhead, while the various shutdown modes significantly reduce the device current consumption for power-critical applications. These devices feature low Differential Nonlinearity (DNL) error to sustain monotonic output and low Integral Nonlinearity (INL) error for better linearity. They are also specified to operate in extended-temperature conditions.
