The MCP4726A0T-E/CH is a single-channel 12-bit digital-to-analog converter from Microchip in a 6-pin SOT-23 package. It uses an I2C two-wire serial interface and provides a unipolar voltage output with a 6 us settling time. The device operates from a 2.7 V to 5.5 V single supply drawing 210 uA nominal, across a -40 C to +125 C temperature range. The body measures 3.1 x 1.8 x 1.3 mm.

Small I2C DACs generate analog setpoints, bias voltages, offset and gain trim, and programmable references in sensor conditioning, motor control, portable instruments and industrial transmitters. A 6-pin SOT-23 body puts a full 12-bit DAC in roughly the area of a transistor, which is why it appears wherever an analog control voltage is needed but a dedicated DAC would otherwise be unjustifiable on space grounds. Industrial, medical and portable instrument designers are the typical buyers. An integral nonlinearity of 14.5 LSB appears in this listing's attributes, which is inconsistent with the rest of the specification, so confirm the INL and DNL figures against the Microchip datasheet where accuracy is critical.
