1N4901

Overview

The MCP4901-E/P is a single-channel, 8-bit digital-to-analog converter (DAC) manufactured by Microchip Technology. It features a resistor-string architecture with a buffered voltage output and supports serial interfaces including SPI, Microwire, and 3-wire protocols. The device operates on a single supply voltage ranging from 2.7 V to 5.5 V for both analog and digital domains. It offers a typical settling time of 4.5 µs and is housed in an 8-pin PDIP package. The component is qualified under AEC-Q100 standards and functions within a temperature range of -55°C to +125°C.

Feature Summary

• Provides a buffered voltage output suitable for driving low-impedance loads without external amplification.
• Supports standard serial communication protocols including SPI, Microwire, and 3-wire interfaces for flexible system integration.
• Operates across a wide industrial temperature range and meets automotive qualification requirements.

Applications

• Battery-powered instrumentation systems requiring low power consumption.
• Programmable gain amplifier offset adjustment circuits.
• Portable test equipment and data acquisition modules.

Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm package type and temperature grade. Ensure the ordering part number matches the required interface configuration and that the source provides valid traceability for AEC-Q100 compliance if automotive use is intended.

Selection Notes

Select this component when a single-channel, 8-bit resolution DAC is required with a buffered output stage. Consider the PDIP-8 package for through-hole assembly needs and verify that the 2.7V to 5.5V supply range aligns with the system's power architecture.

Part Context

This device belongs to the MCP4901 family of single-channel DACs. It shares core functional specifications with other variants in the series, differing primarily in packaging options such as surface-mount DFN or MSOP formats and specific temperature ranges defined by their suffix codes.

Replacement Considerations

Direct replacements include other MCP4901 variants with different packages, such as MCP4901-E/MC or MCP4901-E/MS, provided pin compatibility and thermal performance meet the design requirements.
