Microchip Technology has announced the MCP4725 Digital-to-Analog Converter (DAC), which is said to be 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.
Non-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.
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 PICkit Serial Analyzer, or independently with the customer's application board. It can be purchased today, for $15, at www.microchipdirect.com.
