Microchip 8-Bit 2-Channel SPI Digital-to-Analogue Converter 10-Pin MSOP MCP48FVB02-E/UN

The Microchip MCP48FVB02-E/UN is an 8-bit resolution, 2-channel digital-to-analogue converter (DAC) designed to provide high accuracy and fast response in a compact 10-pin MSOP package. It features a resistor string architecture with rail-to-rail voltage output ensuring the maximum analogue voltage swing over the supply range. This DAC integrates a versatile SPI communication interface supporting command write speeds of up to 20 MHz and read speeds of up to 10 MHz for efficient data transfer in embedded designs.

With a typical settling time of 7.8 microseconds, the DAC is suitable for applications demanding rapid signal updates such as industrial instrumentation, control systems, and data acquisition. The device supports multiple voltage reference configurations including the device power supply voltage (VDD), external buffered or unbuffered VREF options, and an internal bandgap reference of approximately 1.22 V, allowing flexibility in output voltage scaling.

Operating with a supply voltage range from 1.8 V to 5.5 V, the MCP48FVB02-E/UN ensures compatibility with a wide range of system voltages while maintaining low power consumption - maximum normal operation current is 180 microamps, and power down mode reduces consumption to approximately 650 nanoamps.

The small footprint (3 mm length x 3 mm width x 1.1 mm height) and surface mount package (MSOP) facilitate high-density PCB layouts in space-constrained applications. This DAC is ideal for analogue output generation in embedded systems, signal conditioning modules, and precision control loops.

8-bit output voltage resolution with 256 steps. Resistor string architecture for accurate voltage output. Dual-channel output for multi-signal applications. Multiple voltage reference options including internal bandgap. Fast settling time of 7.8 μs (typical) for high-speed DAC updates.

Low power consumption with power-down functionality. Compact 10-pin MSOP surface mount package. Wide operating temperature range from -40°C to 125°C. SPI interface compatible with high-speed serial communication.

This product is widely used across electronic industrial devices, embedded controllers, instrumentation equipment, and data acquisition systems where precise digital-to-analogue conversion is critical.
