MCP48FEB21 is a single channel, 12-bit, voltage output Digital-to-Analog Converter with EEPROM and an SPI Compatible Serial Interface. This device provides four different voltage reference options: device VDD, external VREF (buffered or unbuffered) and internal bandgap. It offers high AC performance, low power consumption and fast settling time. The device has integrated EEPROM to save DAC settings at power down. It is suitable for consumer and industrial applications, such as set point control, offset adjustment and sensor calibration applications, and portable instruments.
For different resolutions and number of output channels, please check out our other parts in the MCP48FE family.

 This blank Printed Circuit Board allows 8- and 10-pin devices in the following package types to be installed: MSOP-10, MSOP-8 and DIP-10.This board is generic so that any of the listed devices may be installed. Refer to the device data sheet, however, for suitability of device evaluation.As well as the device, other desired passive components (resistors and capacitors) and connection posts may be installed. This allows the board to evaluate a minimum configuration for the device. |
