D/A-konverter opretholder opsætninger med intern EEPROM
Microchip annoncerer ny D/A-konverter med integreret EEPROM, der kan opretholde opsætningsdata, selvom power er afbrudt (in english).
Microchip Technology has expanded its digital-to-analog converter (DAC) product line with the MCP48FXBXX families of devices. 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 don’t require integrated memory.These low-power, single and dual-channel DACs feature 8, 10 and 12-bit resolution, a SPI serial interface, and are available in 10-pin MSOP packages. Examples of their wide range of applications in the consumer, industrial and automotive markets, among others, include set-point/offset trimming, sensor calibration, instrumentation, and motor control.
- These new MCP48FXBXX DAC families are ideal for portable, consumer and handheld applications that demand low power consumption. They are also specified to operate in extended-temperature conditions, making them suitable for many industrial and automotive requirements, as well, says Bryan J. Liddiard, marketing vice president of Microchip’s Mixed-Signal and Linear Division.
The high integration and unique feature sets of the MCP48FXBXX families offer customers flexibility, power and cost savings while simplifying their design efforts. 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. Additionally, these devices feature low Differential Nonlinearity (DNL) error to sustain monotonic output and low Integral Nonlinearity (INL) error for better linearity.
The MCP48FXBXX DAC families are available now for sampling and volume production in 10-pin MSOP packages.
