They are supplied in miniature 2 mm x 2 mm DFN or 6-pin SOT-23 packages. These DACs will allow designers to develop more creative designs and meet size and cost reduction goals in consumer applications such as wireless microphones and MP3 player accessories, as well as in industrial applications such as motor control, flow measurement, temperature control, and lighting control.

 

The integrated EEPROM allows the DAC settings to be recalled upon power connection for greater system flexibility. The option of 8, 10, or 12-bit resolution provides flexibility in striking the right balance between functionality and cost, while the buffered output allows for selectable gain of 1 or 2 and offers rail-to-rail output. Low power consumption of 210 µA extends battery life, and the available small packages reduce the printed circuit board footprint.

To expedite the development of MCP47x6 DACs, the $24.99 PICtail™ Plus daughterboard (ADM00317) incorporates the 8-bit MCP4706, 10-bit MCP4716, and 12-bit MCP4726. The board allows connection of the Explorer 16 Starter Kit (DV164033) for 16- and 32-bit PIC® microcontrollers or the PICkit™ Serial Analyzer (DV164122) to read and write DAC registers using the PICkit Serial Analyzer PC software.
