Description

The MCP4801/4811/4821 devices are single channel

8-bit, 10-bit and 12-bit buffered voltage output

Digital-to-Analog Converters (DACs), respectively. The

devices operate from a single 2.7V to 5.5V supply with

an SPI compatible Serial Peripheral Interface.

The devices have a high precision internal voltage

reference (V

REF

= 2.048V). The user can configure the

full-scale range of the device to be 2.048V or 4.096V by

setting the Gain Selection Option bit (gain of 1 of 2).

The devices can be operated in Active or Shutdown

mode by setting a Configuration register bit or using the

SHDN

pin. In Shutdown mode, most of the internal

circuits, including the output amplifier, are turned off for

power savings, while the amplifier output (V

OUT

) stage is

configured to present a known high resistance output

load (500 k typical.

The devices include double-buffered registers,

allowing a synchronous update of the DAC output

using the LDAC

pin. These devices also incorporate a

Power-on Reset (POR) circuit to ensure reliable power-

up.

The devices utilize a resistive string architecture, with

its inherent advantages of low DNL error, low ratio

metric temperature coefficient and fast settling time.

These devices are specified over the extended

temperature range (+125°C).

The devices provide high accuracy and low noise

performance for consumer and industrial applications

where calibration or compensation of signals (such as

temperature, pressure and humidity) are required.

The MCP4801/4811/4821 devices are available in the

PDIP, SOIC, MSOP and DFN packages.
