MCP48CVB08-20E/ST

Digital To Analog Converters Overview

The MCP48CVB08-20E/ST is an octal-channel, 8-bit Digital-to-Analog Converter (DAC) featuring buffered voltage outputs and volatile memory. It operates on a single supply ranging from 2.7V to 5.5V, with reduced specifications available between 1.8V and 2.7V. The device utilizes a 3-wire SPI serial interface supporting clock speeds up to 50 MHz for write operations and 25 MHz for reads. Key electrical characteristics include a typical settling time of 4 µs, a maximum Integral Nonlinearity (INL) of ±1 LSB, and a gain error of ±0.6% of Full Scale Range (FSR). It incorporates Power-on Reset (POR) and Brown-out Reset (BOR) protection, selectable output gain (1x or 2x), and multiple power-down modes.

Digital To Analog Converters Feature Summary

• Octal configuration providing eight independent buffered analog voltage outputs within a single package.
• Integrated volatile memory architecture allowing rapid data updates without nonvolatile storage overhead.
• High-speed SPI serial interface compatible with standard '00' and '11' modes for efficient digital control.
• Flexible reference input options including internal band gap, external VREF pin, or direct VDD connection.

Digital To Analog Converters Applications

• Set point or offset trimming in industrial control systems
• Sensor calibration circuits requiring multi-channel adjustment
• Low-power portable instrumentation devices
• Data acquisition systems with multiple analog channels
• Motor control applications needing precise voltage references

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature range. Ensure the component matches the exact resolution and channel count required for the design. Cross-reference the part number with official Microchip Technology documentation to validate active status and compliance standards before finalizing procurement.

Digital To Analog Converters Selection Notes

Select this component when a high channel count is required in a compact footprint. The volatile memory option is suitable for applications where power-up defaults are managed by the host system. Consider the 1 LSB INL specification for precision requirements. Evaluate the SPI speed limits against the microcontroller capabilities to ensure reliable communication at the desired update rates.

Digital To Analog Converters Part Context

This device belongs to the MCP48CXBX4/8 family of multi-channel DACs. The 'C' indicates the 8-bit resolution variant, while 'VB' denotes the volatile memory configuration. The '08' specifies the octal channel count. This family shares architectural similarities with other Microchip DACs but is distinct in its combination of channel density and interface speed.

Digital To Analog Converters Replacement Considerations

Direct replacements within the same family include MCP48CVB04-20E/ST for quad-channel applications. For nonvolatile memory requirements, consider the MCP48CMB08 series. Verify that any substitute maintains the same SPI timing parameters and output buffer characteristics to ensure circuit compatibility.
