General Description  
• Power-on/Brown-out Reset Protection  
• Power-Down Modes:  
The MCP48FVBXX are Single- and Dual-channel 8-bit,  
10-bit, and 12-bit buffered voltage output  
Digital-to-Analog Converters (DAC) with volatile  
memory and an SPI serial interface.  
- Disconnects output buffer (High Impedance)  
- Selection of VOUT pull-down resistors  
(100 kor 1 k)  
• Low Power Consumption:  
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.  
- Normal operation: <180 µA (Single),  
380 µA (Dual)  
- Power-down operation: 650 nA typical  
• SPI Interface:  
- Supports ‘00’ and ‘11’ modes  
- Up to 20 MHz writes and 10 MHz reads  
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.  
- Input buffers support interfacing to  
low-voltage digital devices  
• Package Types: 10-lead MSOP  
• Extended Temperature Range: -40°C to +125°C  
Applications  
• Set Point or Offset Trimming  
• Sensor Calibration  
• Low-Power Portable Instrumentation  
• PC Peripherals  
• Data Acquisition Systems  
• Motor Control
