The MCP4802-E/SN is a dual 8-bit buffered voltage output Digital-to-analog Converter (DAC) operates from a single 2.7 to 5.5V supply with SPI compatible serial peripheral interface. The device has a high precision internal voltage reference. The 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 device includes double-buffered registers, allowing synchronous updates of two DAC outputs using the LDAC pin. This device also incorporates a power-on reset (POR) circuit to ensure reliable power-up. The device utilizes resistive string architecture with its inherent advantages of low DNL error, low ratio metric temperature coefficient and fast settling time. This device is specified over the extended temperature range.
- SPI interface with 20MHz clock support
- Simultaneous latching of the dual DAC with LDAC pin
- Fast settling time of 4.5µs
- Selectable unity or 2x gain output
- 50ppm/°C VREF Temperature coefficient
