Microchip 12-Bit 2-Channel SPI Digital to Analogue Converter, 10-Pin MSOP MCP48FVB22-E/UN

Microchip MCP48FVB22-E/UN is a 12-bit Digital to Analogue Converter (DAC) featuring two output channels, designed for precision and low-power industrial applications. Packaged in a small 10-Pin MSOP form factor with dimensions 3 mm length, 3 mm width, and 1.1 mm height, this surface mount device operates on supply voltages ranging from 1.8 V to 5.5 V and covers a broad operating temperature from -40°C to 125°C.

Its resistor string architecture provides reliable and accurate digital to analog conversion with 4096 distinct voltage steps. The SPI interface supports fast data transfer with write operations up to 20 MHz and read up to 10 MHz, enabling efficient integration into microcontroller and DSP systems.

The device offers flexible voltage reference options including an internal bandgap voltage (1.22 V typical), external buffered or unbuffered VREF inputs, and the device supply voltage VDD, facilitating adaptability to various system requirements. Output gain can be configured either as unity gain (1x) or a gain of 2x when not powered by internal VDD as the voltage source.

Power efficiency is a key feature with a maximum current consumption of 180 µA in normal mode and as low as 650 nA in power-down state, making it suitable for battery-powered and energy-conscious designs. Its fast settling time of 7.8 microseconds ensures rapid signal changes are accurately tracked.

These DACs are ideally suited for applications in industrial control, instrumentation, data acquisition systems, and digital audio equipment where compact size, precision output, and low power usage are critical. The device does not carry any specific automotive or industry certifications but excels in performance within general electronic and semiconductor environments.

Offers 12-bit output voltage resolution with 4096 steps for precise analog signal generation. Provides dual-channel outputs for versatile analog interfacing. SPI interface supports communication speeds up to 20 MHz write and 10 MHz read.

Operates over a wide voltage range from 1.8 V to 5.5 V with single supply mode. Fast settling time of 7.8 microseconds allows quick response times in circuits. Includes multiple voltage reference options and configurable output gain.

Low power consumption suitable for portable and industrial electronics. Wide operating temperature range from -40°C to +125°C for harsh environments. Compact 10-pin MSOP surface mount package ideal for space-limited designs.
