Product Description
Microchip MCP48FEB21-E/UN is a high-performance 12-bit digital-to-analogue converter (DAC) designed for precision voltage output with an SPI interface in a 10-pin MSOP package. Offering a single output channel, it is ideal for industrial, laboratory, and embedded electronic applications requiring accurate analog voltage signals.
This DAC features resistor string architecture with 4096 discrete output steps delivering rail-to-rail output voltage. It provides fast settling time of 7.8 microseconds (typical) which supports rapid waveform generation and control response. The device also supports multiple voltage reference options to enhance flexibility: the device supply voltage (VDD), an external buffered or unbuffered voltage reference, or an internal bandgap reference with approximately 1.22 V typical voltage.
The integrated non-volatile EEPROM enables user settings to be preserved during power-down states, streamlining system startup and calibration. With low power consumption of 180 µA in normal operation and ultra-low 650 nA in power-down mode, this DAC supports battery-powered and energy-conscious applications.
The MCP48FEB21-E/UN is compact (3 mm length × 3 mm width × 1.1 mm height) surface-mount device (SMD) ideal for space-constrained designs. It operates reliably in harsh industrial temperature ranges from -40°C to 125°C, ensuring robustness in tough environments.
The device communicates via an SPI interface capable of write speeds up to 20 MHz and read speeds up to 10 MHz, facilitating fast digital control. Output gain can be selected as unity (1x) or 2x when voltage source is not internal VDD, providing additional design versatility.
Packaging and pin count (10-pin MSOP) support easy integration into complex PCBs for industrial and consumer electronics.
This DAC is suitable for industrial automation, instrumentation, control systems, digital signal processing, and other electronic applications requiring accurate DAC conversion from digital commands to analogue voltages. It is listed under the Digital to Analogue Converter category in semiconductor devices suitable for surface mounting.
