Power-on/Brown-out Reset Protection Power-Down Modes: - Disconnects output buffer (High Impedance) General Description - Selection of V pull-down resistors OUT The MCP47FVBXX are Single- and Dual-channel 8-bit, (100 k or 1 k ) 10-bit, and 12-bit buffered voltage output Digital-to- Low Power Consumption: Analog Converters (DAC) with volatile memory and an 2 - Normal operation: <180 A (Single), 380 A I C serial interface. (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.
