• MCP48FEB21/22 12 Bit Digital-to-Analogue Converters. The Microchip MCP48FEB21/22 family are 12-bit voltage output Digital-to-Analogue Converters (DACs) that offer high performance with low power consumption and fast settling time. On-board Non-Volatile EEPROM can save DAC settings during power down; four different Voltage Reference options are available. An SPI Interface supports write commands up to 20 MHz and read commands of up to 10 MHz. Features. 12-Bit Output Voltage Resolution (4096 steps) Rail-to-Rail Output Fast Settling Time: 7.8 μs (typical) DAC Voltage Reference Options: Device VDD, External VREF (buffered or unbuffered) and Internal Bandgap (1.22 V typical) Output Gain Options: Unity (1x), 2x (when not using internal VDD as voltage source) Non-Volatile Memory (EEPROM) Power-Down modes Low-Power Consumption: 180 μA Normal Operation (maximum), 650 nA Power Down Operation (typical) Single-Supply Operation: 2.7 V to 5.5 V SPI Interface
