General Description
- Selection of VOUT pull-down resistors
The MCP47FVBXX 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
I2C serial interface.
(100 k or 1 k)
• Low Power Consumption:
- Normal operation: <180 µA (Single), 380 µA
(Dual)
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.
- Power-down operation: 650 nA typical
• I2C™ Interface:
- Slave address options: four predefined
addresses
- Standard (100 kbps), Fast (400 kbps), and
High-Speed (up to 3.4 Mbps) modes
- High Voltage Command Support
(MCP47FEBXX compatibility)
These devices have a two-wire I2C-compatible serial
interface for Standard (100 kHz), Fast (400 kHz) or
High-Speed (1.7 MHz and 3.4 MHz) modes.
• Package Types: 8-lead TSSOP
