MCP48CVB22-E/UN

Digital To Analog Converters Overview

The MCP48CVB22-E/UN is a dual-channel, 12-bit volatile Digital-to-Analog Converter (DAC) manufactured by Microchip Technology. It features buffered voltage outputs and communicates via a four-wire SPI serial interface supporting write speeds up to 50 MHz and read speeds up to 25 MHz. The device operates within an analog and digital supply voltage range of 1.8 V to 5.5 V. It includes power-on/brown-out reset protection and configurable power-down modes that disconnect the output buffer or select pull-down resistors. The component is housed in a 10-lead MSOP package and supports an extended operating temperature range from -40°C to +125°C.

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and temperature grade. Ensure the selected variant matches the required memory volatility and interface specifications for the target design. Cross-reference the datasheet revision date to validate all electrical characteristics and timing parameters before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when a dual-channel solution with high-resolution output is required alongside fast SPI communication. Consider the available reference voltage sources and gain configurations to match the system's dynamic range requirements. Evaluate the power consumption in active and power-down modes to ensure compatibility with the application's energy constraints and thermal management capabilities.

Digital To Analog Converters Part Context

This device belongs to the MCP48CXBXX family of 8, 10, and 12-bit DACs. The CVB designation indicates volatile memory retention, distinguishing it from the CMB series which utilizes nonvolatile MTP memory. The UN suffix identifies the specific 10-lead MSOP packaging option suitable for surface-mount assembly in compact electronic designs.

Digital To Analog Converters Replacement Considerations

Direct substitutes within the same family include other MCP48CVB2X variants with different package types such as QFN or DFN. Devices with lower resolution like the MCP48CVB12 may serve as alternatives if reduced precision is acceptable. Verify pinout compatibility and electrical specifications before implementing any cross-model replacements.
