MCP48FEB18T-16E/ST

Digital To Analog Converters Overview

The MCP48FEB18T-16E/ST is an octal-channel, 10-bit digital-to-analog converter (DAC) manufactured by Microchip Technology. It utilizes an R-2R resistor string architecture and features nonvolatile EEPROM memory for data retention. The device supports the SPI serial interface and provides buffered voltage outputs. It operates on a single supply voltage ranging from 1.8 V to 5.5 V for both analog and digital domains. Key performance metrics include a settling time of 7.8 µs, differential nonlinearity (DNL) of ±0.05 LSB, integral nonlinearity (INL) of ±0.4 LSB, and a gain error of 0.1% FSR. The component is housed in a TSSOP-16 package and functions within a temperature range of -40°C to +125°C.

Digital To Analog Converters Feature Summary

• Integrates eight independent DAC channels with 10-bit resolution in a compact surface-mount package.
• Retains output settings through integrated EEPROM, ensuring state preservation during power cycles.
• Provides buffered analog outputs capable of driving loads directly without external amplification.

Digital To Analog Converters Applications

• Multi-zone industrial process control systems requiring simultaneous analog adjustments.
• Portable instrumentation devices needing low-power, multi-channel signal generation.
• Automotive electronic modules operating across extended temperature ranges.

Digital To Analog Converters Procurement Notes

Verify the specific suffix '16E' against the official Microchip datasheet to confirm pinout compatibility and electrical specifications. Ensure the ordering quantity aligns with the manufacturer's reel packaging requirements. Confirm that the intended application environment falls within the specified -40°C to +125°C operational temperature limits. Validate that the system voltage remains within the 1.8 V to 5.5 V range for proper device functionality.

Digital To Analog Converters Selection Notes

Select this component when multiple isolated analog outputs are required from a single controller. The SPI interface reduces pin count compared to parallel alternatives. The nonvolatile memory eliminates the need for external storage or initialization sequences after power-up. Consider the TSSOP-16 footprint constraints during PCB layout design to ensure adequate thermal dissipation and trace routing space.

Digital To Analog Converters Part Context

This part belongs to the MCP48FEB family of octal DACs, designed for applications demanding high channel density and data persistence. It complements volatile variants like the MCP48CVB series by offering built-in memory. The device serves as a bridge between digital control logic and analog actuator requirements in space-constrained designs.

Digital To Analog Converters Replacement Considerations

Direct substitutes include other octal DACs from the same family, such as the MCP47FEB18T-16E/ST, which differs primarily in its I2C interface instead of SPI. Verify interface compatibility before swapping. Alternative packages may require schematic modifications due to pin reassignment.
