12-bit DAC integrates EEPROM in small package

Chandler, Ariz. — Microchip Technology Inc. has released the MCP4725 digital-to-analog converter (DAC), which the company claims is the industry's first DAC to combine an integrated EEPROM and 12-bit resolution in a miniature 6-pin SOT-23 package. The low-power, single-channel DAC offers a buffered voltage output and is suitable for space-constrained portable and battery-powered applications.

Non-volatile EEPROM enables MCP4725 DAC settings to be recalled at power up, which means a microcontroller is not required if the DAC output does not need to change, said Microchip. As a result, it provides flexibility for system designers and helps to reduce cost, power consumption and design footprint.

The DAC delivers low-power consumption of 0.06 microamperes in shutdown, which helps extend battery life. In addition, its onboard precision output amplifier enables a rail-to-rail analog output, so the DAC output fully utilizes the entire voltage range.

The MCP4725 DAC may be used in applications such as consumer (personal media players, digital cameras, GPS devices and hair dryers), medical (portable glucose meters, blood pressure and heart-rate monitors), industrial (handheld instruments, motor control, and temperature and light control), appliance (washing machines and espresso machines), and automotive (LED lamps and alarm/security systems) electronics.

The MCP4725 Evaluation Board is available to help designers evaluate the MCP4725 DAC in their applications. The board works with Microchip's PICkit Serial Analyzer, or independently with the customer's application board.

Pricing: The DAC is priced at $0.67 each in quantities of 10,000. The MCP4725 Evaluation Board (Part # MCP4725EV) can be purchased for $15. Both are available for purchase at www.microchipdirect.com.
