Description

The MCP4802/4812/4822 devices are dual 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 SPI compatible

Serial Peripheral Interface.

The devices have a high precision internal voltage

reference (VREF = 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).

Each DAC channel can be operated in Active or

Shutdown mode individually by setting the Configuration

circuits in the shutdown channel are turned off for power

savings and the output amplifier is configured to present

a known high resistance output load (500 k typical.

The devices include double-buffered registers,

allowing synchronous updates of two DAC outputs

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 MCP4802/4812/4822 devices are available in the

PDIP, SOIC and MSOP packages.
