Microchip Introduces MCP4725 Digital-to-Analog Converter

Microchip Technology Inc., a leading provider of microcontroller and analog semiconductors, announced the MCP4725 Digital-to-Analog Converter (DAC)-the industry’s first DAC to combine integrated EEPROM and 12-bit resolution in a miniature, 6-pin SOT-23 package. The low-power, single-channel DAC has a buffered voltage output and is ideal for space-constrained portable and battery-powered applications found in a variety of markets.

Microchip MCP4725 DACNon-volatile EEPROM enables MCP4725 DAC settings to be recalled at power up, meaning a microcontroller is not required if the DAC output does not need to change. This provides flexibility for system designers and helps to reduce cost, power consumption and design footprint. The highly-accurate DAC has low power consumption of just 0.06 microamperes in shutdown, which helps extend battery life. Additionally, its onboard precision output amplifier enables a rail-to-rail analog output, so the DAC output fully utilizes the entire voltage range.

“Microchip has utilized its expertise in both non-volatile memory and mixed-signal technology to provide added flexibility to customers with the MCP4725 DAC,” said Bryan Liddiard, vice president of marketing with Microchip’s Analog & Interface Products Division.

“Being the first 12-bit DAC in the industry to integrate EEPROM in the 6-pin SOT-23 package, the MCP4725 is expected to help designers meet cost and size constraints, while providing the resolution and low power consumption that today’s portable and battery-powered electronic devices require,” continued Jefferay Lawton, product marketing engineer with Microchip’s Analog & Interface Products Division.

The MCP4725 DAC is appropriate for markets and 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 applications, and temperature and light control); appliance (washing machines and espresso machines); and automotive (LED lamps and alarm/security systems) electronics.

Development Tool Support
The MCP4725 Evaluation Board (Part # MCP4725EV) is available to help designers quickly evaluate the MCP4725 DAC in their applications. The board works with Microchip’s popular PICkit(TM) Serial Analyzer, or independently with the customer’s application board. It can be purchased today, for $15.
