Microchip 12-Bit Serial I2C Digital-to-Analogue Converter DAC, 1 Channel, Surface Mount, 8-Pin TSSOP MCP47FEB21A0-E/ST

Microchip MCP47FEB21A0-E/ST is a high-performance 12-bit Digital-to-Analogue Converter (DAC) featuring a resistor string architecture and a buffered voltage output. It supports a Serial I2C communication interface and comes in a compact 8-pin TSSOP surface mount package measuring 4.5mm by 3.1mm by 1.2mm, making it suitable for space-constrained designs.

This DAC operates from a minimum supply voltage of 1.8V up to 5.5V, supporting single-supply operation with low power consumption. Its fast settling time of 6 microseconds ensures quick response suitable for real-time applications. The device is rated for a wide operational temperature range from -40°C to 125°C, providing robust performance in industrial and automotive environments.

Featuring non-volatile EEPROM memory, it allows retention of DAC settings after power-down, offering flexible power management options including power-down modes and low current consumption states. The output gain can be configured either as unity (1x) or 2x depending on the voltage reference used, enhancing versatility.

With its Serial-I2C interface, this DAC integrates seamlessly with microcontrollers and digital signal processors, making it ideal for embedded system designs, instrumentation, and control systems requiring precise analog voltage outputs.

Typical use cases include industrial automation, laboratory instrumentation, and consumer electronics where digital control over analog signals is required. The device does not carry specific automotive standards certification but is suitable for general industrial applications.
