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 V_OUTpull-down resistors

(100 k or 1 k)

• Low Power Consumption:

The V_REFpin, the device V_DDor the internal band gap

voltage can be selected as the DAC’s reference

voltage. When V_DDis selected, V_DDis connected

internally to the DAC reference circuit. When the V_REF

pin is used, the user can select the output buffer’s gain

to be 1 or 2. When the gain is 2, the V_REFpin voltage

should be limited to a maximum of V_DD/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
