MCP4821/MCP4822

12-Bit DACs with Internal V_REFand SPI™ Interface

Features

Description

• 12-Bit Resolution

The Microchip Technology Inc. MCP482X devices are

2.7V–5.5V, low-power, low DNL, 12-bit Digital-to-Analog

Converters (DACs) with internal band gap voltage

reference, optional 2x-buffered output and Serial

Peripheral Interface (SPI™).

• ±0.2 LSb DNL (typ.)

• ±2 LSb INL (typ.)

• Single or Dual Channel

• Rail-to-Rail Output

The MCP482X family of DACs provide high accuracy

and low noise performance for industrial applications

where calibration or compensation of signals (such as

temperature, pressure and humidity) are required.

• SPI™ Interface with 20 MHz Clock Support

• Simultaneous Latching of the Dual DACs

with LDAC pin

• Fast Settling Time of 4.5 µs

The MCP482X devices are available in the extended

temperature range and PDIP, SOIC and MSOP

packages.

• Selectable Unity or 2x Gain Output

• 2.048V Internal Band Gap 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 MCP482X 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. The MCP482X family

includes double-buffered registers, allowing simulta-

neous updates 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
