MCP47CMB18T-20E/ST

Digital To Analog Converters Overview

The MCP47CMB18T-20E/ST is a single-channel, 10-bit buffered voltage output Digital-to-Analog Converter (DAC) manufactured by Microchip Technology. It features Multi-Time Programmable (MTP) nonvolatile memory and an I2C serial interface. 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 supports Standard (100 kbps), Fast (400 kbps), and High-Speed (up to 3.4 Mbps) I2C modes. The DAC utilizes an R-2R resistor ladder architecture and includes internal power-on/brown-out reset protection. It is housed in a TSSOP-20 package.

Digital To Analog Converters Feature Summary

• Integrates MTP nonvolatile memory allowing up to 32 user-programmable writes per register location using a high-voltage LAT/HVC pin.
• Provides flexible reference voltage options including VDD, external VREF pin, or an internal band gap source.
• Supports configurable output gain settings of 1x or 2x when utilizing the external VREF pin.

Digital To Analog Converters Applications

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

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and tape-and-reel configuration. Ensure the selected variant matches the required operating temperature range and memory type. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current availability status and lead times before finalizing procurement plans.

Digital To Analog Converters Selection Notes

Select this component for designs requiring persistent DAC output states without external storage. Verify that the system can provide the necessary high-voltage level on the LAT/HVC pin for MTP programming. Confirm that the I2C bus speed requirements align with the device's Standard, Fast, or High-Speed mode capabilities.

Digital To Analog Converters Part Context

This model belongs to the MCP47CXBXX family of 8-bit, 10-bit, and 12-bit DACs. The 'CMB' designation indicates the inclusion of MTP nonvolatile memory, distinguishing it from volatile RAM variants. The '18' suffix specifies the 10-bit resolution, while '20E/ST' denotes the TSSOP-20 package and extended industrial temperature rating.

Digital To Analog Converters Replacement Considerations

Direct functional substitutes within the same family include other MCP47CXBXX variants with matching channel counts and resolutions. For single-channel 10-bit applications, verify compatibility with MCP47CMB11 or MCP47CVB11 depending on memory requirements.
