產品總覽

The MCP4912-E/SL is a dual 10-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 user can configure the full-scale range of the device to be VREF or 2x VREF by setting the gain selection option bit. The user can shut down both DAC channels by using SHDN pin or shut down the DAC channel 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 and fast settling time.
  • Rail-to-rail output
  • 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
  • External voltage reference input
  • External multiplier mode
