The MCP4802 device is 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 device has 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 register bits. In Shutdown mode, most of the internal 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. 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 powerup. The devices utilize a resistive string architecture, with its inherent advantages of low DNL error, low ratiometric temperature coefficient, and fast settling time. These devices are specified over the extended temperature range (+125°C).

The device provides 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.

Application:
  1. SetPoint or Offset Trimming
