Microchip 12-Bit Voltage Output Digital to Analogue Converter SPI Interface 10-Pin MSOP MCP48FEB21-E/UN

The Microchip MCP48FEB21-E/UN is a 12-bit Digital to Analogue Converter (DAC) designed to deliver high precision voltage output with fast settling times and low power consumption. Featuring a resistor string architecture and a surface mount 10-pin MSOP package, it operates with a voltage supply range from 1.8 V minimum to 5.5 V maximum, making it suitable for a wide range of electronic applications requiring reliable digital-to-analog signal conversion.

This DAC is equipped with an SPI interface supporting write operations up to 20 MHz and read operations up to 10 MHz, facilitating efficient integration with microcontrollers and other digital systems. The on-board non-volatile EEPROM memory allows storage of DAC settings across power cycles, enhancing system reliability and preserving voltage output configurations.

Key performance characteristics include a 12-bit resolution with 4096 discrete steps, rail-to-rail output capability, and a typical settling time of 7.8 microseconds. It offers versatile DAC voltage reference options such as device VDD, external buffered or unbuffered VREF, and an internal bandgap reference of approximately 1.22 V. Output gain options include unity (1x) and 2x, permitting flexibility in signal scaling when not using internal VDD as the voltage source.

The device supports single-supply operation between 2.7 V to 5.5 V, delivering low power consumption with typical 180 µA during normal operation and 650 nA in power-down modes. It is designed to operate reliably in temperatures from -40°C to 125°C, broadening its applicability for industrial, automotive, instrumentation, and general electronic applications.

Applications include industrial control systems, data acquisition, sensor interfacing, and anywhere precise analog output is necessary. The compact MSOP package with dimensions 3 mm length, 3 mm width, and 1.1 mm height facilitates space-saving circuit designs. The product does not hold automotive standards compliance but meets robust non-automotive standards for dependable performance.

Offers a 12-bit output voltage resolution with 4096 discrete steps. Features a rail-to-rail output for maximum signal swing. Fast typical settling time of 7.8 microseconds to improve signal response. Multiple DAC voltage reference options including device VDD, external VREF, and internal bandgap reference.
