12bit DAC takes nonvolatile memory onboard

Low-power single-channel DAC has a buffered voltage output and is ideal for space-constrained and battery-powered applications.

According to Microchip, the MCP4725 is the industry's first DAC to combine 12bit resolution and an integrated EEPROM 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 and battery-powered applications found in a variety of markets.

Using Microchip's expertise in both nonvolatile memory and mixed-signal technology, the nonvolatile EEPROM enables MCP4725 DAC settings to be recalled at power up, without microcontroller intervention, providing flexibility for system designers and helping to reduce cost, power consumption and design footprint.

For microcontroller connectivity, the device features an I2C interface with a single address selection pin.

The new device has a shutdown current of just 0.06uA, which also helps to extend battery life.

In addition, its precision output amplifier provides a rail-to-rail analogue output, fully utilising the entire supply voltage range.

The MCP4725 evaluation board (Part number MCP4725EV) is available now to help designers quickly evaluate the operation of the MCP4725 DAC.

The new board works with Microchip's PICkit serial analyser, or independently alongside the customer's application.

Samples and production quantities of the MCP4725 DAC are available now.
