Microchip 12 Bit Digital-to-Analogue Converter Resistor String Architecture Serial-I2C Interface 8-Pin MCP47FEB21A0-E/ST

Microchip MCP47FEB21A0-E/ST is a high-precision 12-bit Digital-to-Analogue Converter (DAC) featuring resistor string architecture and a single buffered voltage output channel. Packaged in an 8-pin Thin Shrink Small Outline Package (TSSOP), this device provides accurate, low-noise analogue voltage outputs suitable for industrial, laboratory, and embedded system applications.

This DAC operates over a wide supply voltage range of 1.8 V to 5.5 V, making it adaptable for battery-powered and standard logic-level circuits. It incorporates multiple voltage reference options including the device VDD, external VREF (buffered or un-buffered), and an internal bandgap reference with typical 1.22 V output, offering flexibility in output range and gain settings.

The device features a fast settling time of 6 microseconds, ensuring rapid signal transitions necessary for real-time control and instrumentation systems. Operating temperature spans from -40°C to 125°C, making it robust for automotive, industrial, and harsh environmental conditions.

Non-volatile EEPROM memory allows the device to retain output settings even when powered down, enhancing reliability in power cycling scenarios. Low power consumption modes include typical 180 μA operation current for the single channel variant and ultra-low power down current of 650 nA.

The MCP47FEB21A0-E/ST interfaces via industry-standard Serial-I2C protocol to seamlessly integrate with microcontrollers and digital signal processors, facilitating ease of communication and control.

Utilizes resistor string architecture for stable and accurate conversion. 12-bit resolution enables fine granularity in output voltages. Single buffered output channel reduces signal noise and distortion. Compact 8-pin TSSOP surface-mount package for space-efficient PCB layouts.
