MCP48FVB21T-E/UN

Digital To Analog Converters Overview

The MCP48FVB21T-E/UN is a single-channel, 12-bit volatile Digital-to-Analog Converter (DAC) manufactured by Microchip Technology. It features an SPI serial interface and operates within a supply voltage range of 1.8V to 5.5V. The device provides rail-to-rail buffered voltage output with a typical settling time of 7.8 µs. It supports multiple reference sources including VDD, external VREF, or an internal band gap. Power consumption is low, drawing less than 320 µA during active operation and approximately 650 nA in power-down mode. The component is housed in a 10-lead MSOP package and is qualified for extended industrial temperature ranges from -40°C to +125°C.

Digital To Analog Converters Feature Summary

• Single-channel 12-bit resolution with volatile memory storage
• SPI-compatible serial interface supporting up to 20 MHz write speeds
• Rail-to-rail buffered voltage output capability
• Configurable power-down modes with selectable pull-down resistors

Digital To Analog Converters Applications

• Set point or offset trimming
• Sensor calibration
• Low-power portable instrumentation
• Motor control systems

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix 'T' indicates tape and reel packaging when sourcing this component. Confirm that the '-E' designation corresponds to the extended temperature range specifications required for your application environment. Ensure compatibility with standard SPI logic levels before integration into the design.

Digital To Analog Converters Selection Notes

Select this model for applications requiring a single analog output channel with 12-bit precision. Consider the volatile nature of the memory, which requires re-initialization after power cycles. Evaluate the need for gain settings and reference voltage options to ensure the output range matches the system requirements without exceeding the supply voltage limits.

Digital To Analog Converters Part Context

This part belongs to the MCP48FVBXX family of digital-to-analog converters. It shares architectural similarities with other members like the MCP48FVB02 and MCP48FVB22 but differs in channel count and resolution. The family utilizes a consistent SPI interface and MSOP packaging, allowing for potential pin-compatible upgrades or downgrades depending on specific resolution needs.

Digital To Analog Converters Replacement Considerations

Direct replacements include other variants within the MCP48FVBXX series such as the MCP48FVB01T-E/UN for lower resolution or MCP48FVB11T-E/UN for intermediate resolution. Cross-family alternatives like the MCP47FVB21T-E/ST offer I2C interfaces instead of SPI.
