Package Types

General Description

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.

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
