MCP47CVB18-20E/ST

Digital To Analog Converters Overview

The MCP47CVB18-20E/ST is an octal-channel, 10-bit buffered voltage output Digital-to-Analog Converter (DAC) from Microchip Technology. It features volatile memory and a two-wire I2C serial interface supporting Standard (100 kHz), Fast (400 kHz), and High-Speed (up to 3.4 MHz) modes. The device operates within a supply voltage range of 2.7V to 5.5V for full specifications, or 1.8V to 2.7V with reduced analog performance. It utilizes a TSSOP-20 package and supports an extended operating temperature range from -40°C to +125°C.

Digital To Analog Converters Feature Summary

• Octal-channel architecture providing eight independent buffered voltage outputs in a single integrated circuit.
• I2C compatible serial interface enabling communication via Standard, Fast, and High-Speed modes.
• Configurable voltage reference sources including device VDD, external VREF pin, and internal band gap.
• Integrated power-on and brown-out reset protection to ensure reliable startup conditions.

Digital To Analog Converters Applications

• Set point or offset trimming
• Sensor calibration
• Low-power portable instrumentation
• PC peripherals
• Data acquisition systems

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 component matches the required channel count and resolution for the target design. Cross-reference the datasheet revision date to validate electrical characteristics and timing parameters before finalizing procurement specifications.

Digital To Analog Converters Selection Notes

Select this component when multiple isolated DAC channels are required within a compact footprint. Consider the 10-bit resolution and buffered output capabilities for applications demanding moderate precision without external amplification. Evaluate the I2C bus speed requirements to determine if Standard, Fast, or High-Speed modes are necessary for system throughput.

Digital To Analog Converters Part Context

This part belongs to the MCP47CXBXX family of digital-to-analog converters. The 'CVB' designation indicates volatile memory configuration, distinguishing it from nonvolatile MTP variants. The '18' suffix specifies the octal channel and 10-bit resolution combination, while '20E/ST' denotes the TSSOP-20 package and industrial temperature rating.

Digital To Analog Converters Replacement Considerations

Direct substitutes within the same family include other MCP47CVBxx variants with different channel counts or resolutions. Verify compatibility regarding package dimensions and pinout assignments when considering alternative members of the MCP47CXBXX series.
