MCP48FVB02T-E/UNVAO

Digital To Analog Converters Overview

The MCP48FVB02T-E/UNVAO is a dual-channel, 8-bit volatile Digital-to-Analog Converter (DAC) manufactured by Microchip Technology. It features an SPI serial interface and buffered voltage outputs with rail-to-rail capability. The device operates on supply voltages ranging from 1.8V to 5.5V, with full specifications guaranteed between 2.7V and 5.5V. Key electrical parameters include a typical settling time of 7.8 µs, a maximum DNL of ±0.25 LSB, and INL of ±1.5 LSB. Power consumption is typically 380 µA in normal operation and drops to 650 nA in power-down mode. It supports reference sources including VDD, external VREF, or an internal band gap.

Digital To Analog Converters Feature Summary

• Dual-channel architecture providing two independent 8-bit DAC outputs within a single package.
• SPI-compatible serial interface supporting write speeds up to 20 MHz and read speeds up to 10 MHz.
• Configurable output gain options of 1x or 2x when utilizing the external VREF pin.
• Integrated power-on/brown-out reset protection and selectable power-down modes for low-power applications.

Digital To Analog Converters Applications

• Set point or offset trimming in industrial control systems
• Sensor calibration circuits requiring precise analog signal generation
• Low-power portable instrumentation devices
• Motor control applications needing adjustable voltage references

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'VAO' against official Microchip documentation to confirm automotive qualification status, as standard datasheets may not explicitly detail this suffix variant. Ensure compatibility with AEC-Q100 standards if required for automotive use. Confirm package availability matches the tape-and-reel format indicated by the 'T' in the part number.

Digital To Analog Converters Selection Notes

Select this component for designs requiring dual-channel voltage output with volatile memory storage. Consider the 8-bit resolution limits for precision requirements. Evaluate the need for external versus internal reference voltage based on system accuracy needs. Verify that the SPI interface timing meets the host controller's capabilities, particularly regarding the 20 MHz write speed.

Digital To Analog Converters Part Context

This part belongs to the MCP48FVBXX family of 8-bit, 10-bit, and 12-bit buffered voltage output DACs. The '02' designation indicates a dual-channel configuration with 8-bit resolution. The 'T' suffix denotes tape-and-reel packaging, while 'E' signifies extended temperature range operation. This series offers cost-effective solutions compared to non-volatile EEPROM variants.

Digital To Analog Converters Replacement Considerations

MCP48FVB02-E/UN: Same functional specifications but in tube packaging instead of tape-and-reel.

Digital To Analog Converters FAQ

What are the available reference voltage sources for the MCP48FVB02?

The device supports three reference voltage sources: the device VDD pin, an external VREF pin (buffered or unbuffered), or an internal band gap voltage of approximately 1.22V.

How does the device handle power-down states?

Power-down modes disconnect the output buffer to create a high-impedance state. Users can select between pulling the output down via a 100 kΩ or 1 kΩ resistor, or leaving it floating, depending on the configuration bits.

What is the maximum SPI clock frequency for writes?

The MCP48FVB02 supports SPI write commands at frequencies up to 20 MHz. Read commands are supported up to 10 MHz.
