General Description
The MCP48FEBXX are Single- and Dual-channel 8-bit,
10-bit, and 12-bit buffered voltage output
Digital-to-Analog Converters (DAC) with nonvolatile
memory and an SPI serial interface.
The VREF pin, the device VDD or the internal band gap
voltage can be selected as the DAC’s reference
voltage. When VDD is selected, VDD is connected
internally to the DAC reference circuit. When the VREF
pin is used, the user can select the output buffer’s gain
to be 1 or 2. When the gain is 2, the VREF pin voltage
should be limited to a maximum of VDD/2.
These devices have an SPI-compatible serial interface.
Write commands are supported up to 20 MHz while
read commands are supported up to 10 MHz.
Applications
• Set Point or Offset Trimming
• Sensor Calibration
• Low-Power Portable Instrumentation
• PC Peripherals
• Data Acquisition Systems
• Motor Control
