Description

The MCP4706/4716/4726 are single channel 8-bit,

10-bit, and 12-bit buffered voltage output Digital-to-

Analog Converters (DAC) with nonvolatile memory and

an I

The DAC Register value and configuration bits can be

programmed to nonvolatile memory (EEPROM). The

nonvolatile memory holds the DAC Register and

configuration bit values when the device is powered off.

A device reset (such as a Power On Reset) latches

these stored values into the volatile memory.

Power-down modes enable system current reduction

when the DAC output voltage is not required. The V

pin can be configured to present a low, medium, or high

resistance load.

These devices have a two-wire I

interface for standard (100 kHz), fast (400 kHz), or high

speed (3.4 MHz) mode.

These devices are available in small 6-pin SOT-23 and

DFN 2x2 mm packages.
