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 I2C serial interface. This family will also be referred
to as MCP47X6.
The VREF pin or the device VDD can be selected as the
DAC’s reference voltage. When VDD is selected, VDD is
connected internally to the DAC reference circuit.
When the VREF pin is used, the user can select the
output buffer’s gain to 1 or 2. When the gain is 2, the
VREF pin voltage should be limited to a maximum of
VDD/2.
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 VOUT
pin can be configured to present a low, medium, or high
resistance load.
These devices have a two-wire I2C™ compatible serial
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.
