Microchip Technology MCP47FEB08
The MCP47FXBX4/8 devices are a family of buffered voltage output Digital-to-Analog Converters (DAC), with the following options: • quad or octal output channel configurations • 8/10/12-bit resolution • Volatile or nonvolatile user memory The quad and octal options differ only by the number of output channels. The volatile and nonvolatile versions have an identical analog circuit structure. When the VDD mode is selected, it is internally connected to the DAC’s reference circuit.FEATURES
● Operating Voltage Range: - 2.7V to 5.5V - Full specifications - 1.8V to 2.7V - Reduced device specifications● Output Voltage Resolutions: - 8-bit: MCP47FXB0X (256 steps) - 10-bit: MCP47FXB1X (1024 steps) - 12-bit: MCP47FXB2X (4096 steps)
● Rail-to-Rail Output
● Fast Settling Time of 7.8 µs (Typical)
● DAC Voltage Reference Source Options: - Device VDD - External VREF pin (buffered or unbuffered) - Internal band gap (1.22V typical)
● Output Gain Options: - 1x (unity) - 2x (available when not using internal VDD as voltage source)
● Nonvolatile Memory (EEPROM) Option: - User-programmed Power-on Reset (POR)/Brown-out Reset (BOR) output setting and device Configuration bits recall - Auto recall of saved DAC register setting - Auto recall of saved device configuration (voltage reference, gain, power-down)
● Power-on/Brown-out Reset Protection
● Power-Down Modes: - Disconnects output buffer (high-impedance) - Selection of VOUT pull-down resistors (125 k or 1 k)
● Low-Power Consu...
