MCP4801/4811/4821

8/10/12-Bit Voltage Output Digital-to-Analog Converter

with Internal V_REFand SPI Interface

Features

Description

• MCP4801: 8-Bit Voltage Output DAC

• MCP4811: 10-Bit Voltage Output DAC

• MCP4821: 12-Bit Voltage Output DAC

• Rail-to-Rail Output

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.

• SPI Interface with 20 MHz Clock Support

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).

• Simultaneous Latching of the DAC Output

with LDAC Pin

• Fast Settling Time of 4.5 µs

• Selectable Unity or 2x Gain Output

• 2.048V Internal Voltage Reference

• 50 ppm/°C V_REFTemperature Coefficient

• 2.7V to 5.5V Single-Supply Operation

• Extended Temperature Range: -40°C to +125°C

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.

Applications

• Set Point or Offset Trimming

• Sensor Calibration

• Precision Selectable Voltage Reference

• Portable Instrumentation (Battery-Powered)

• Calibration of Optical Communication Devices

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).
