This family will also be referred - Auto Recall of Saved DAC register setting to as MCP47X6. - Auto Recall of Saved Device Configuration The VREF pin or the device VDD can be selected as the (Voltage Reference, Gain, Power-Down) DAC’s reference voltage. When VDD is selected, VDD is • Power-Down modes: connected internally to the DAC reference circuit. - Disconnects output buffer When the VREF pin is used, the user can select the output buffer’s gain to 1 or 2. When the gain is 2, the - Selection of VOUT pull-down resistors V (640 kΩ, 125 kΩ, or 1 kΩ) REF pin voltage should be limited to a maximum of VDD/2. • Low-Power Consumption: The DAC register value and Configuration bits can be - Normal Operation: 210 µA typical programmed to nonvolatile memory (EEPROM).
