(Dual) The V pin, the device V or the internal band gap REF DD - Power-down operation: 650 nA typical voltage can be selected as the DACs reference 2 I C Interface: voltage. When V is selected, V is connected DD DD - Slave address options: four predefined internally to the DAC reference circuit. When the V REF addresses pin is used, the user can select the output buffers gain to be 1 or 2. When the gain is 2, the V pin voltage - Standard (100 kbps), Fast (400 kbps), and REF should be limited to a maximum of V /2. High-Speed (up to 3.4 Mbps) modes DD 2 - High Voltage Command Support These devices have a two-wire I C-compatible serial (MCP47FEBXX compatibility) interface for Standard (100kHz), Fast (400 kHz) or High-Speed (1.7 MHz and 3.4 MHz) modes.
