MCP47CMB28-20E/ST

Digital To Analog Converters Overview

The MCP47CMB28-20E/ST is an octal-channel, 12-bit buffered voltage output Digital-to-Analog Converter (DAC) featuring Multi-Time Programmable (MTP) nonvolatile memory and an I2C serial interface. It 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. The device integrates a 1.214V internal bandgap reference, selectable external VREF input, and gain options of 1x or 2x. Key electrical parameters include a typical settling time of 16 µs, a maximum Integral Nonlinearity (INL) of ±1 LSB, and a power-down current as low as 0.65 µA. It supports Standard (100 kbps), Fast (400 kbps), and High-Speed (up to 3.4 Mbps) I2C modes.

Digital To Analog Converters Feature Summary

• Integrates MTP nonvolatile memory allowing up to 32 user-programmable writes per register location for persistent data storage.

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 the manufacturer's official documentation to confirm package type and temperature grade. Ensure the selected variant matches the required channel count and memory configuration for the target application design.

Digital To Analog Converters Selection Notes

Select this component when an octal DAC configuration with nonvolatile storage is required. Consider the 12-bit resolution and I2C interface compatibility. Evaluate the operating voltage requirements against the 2.7V to 5.5V specification range for optimal performance.

Digital To Analog Converters Part Context

This part belongs to the MCP47CXBXX family of digital-to-analog converters. The family includes single, dual, quad, and octal channel variants with resolutions ranging from 8-bit to 12-bit. The 'M' in the model number indicates the inclusion of MTP nonvolatile memory, distinguishing it from volatile RAM-based counterparts.

Digital To Analog Converters Replacement Considerations

Direct substitutes within the same family include other MCP47CXBXX variants with matching channel counts and resolutions. Verify pinout compatibility and memory type before substitution.
