MAX35101EHJ+T

Overview

The MAX35101EHJ+T is a Time-to-Digital Converter (TDC) with an integrated Analog Front End (AFE), manufactured by Analog Devices Inc./Maxim Integrated. It operates on a supply voltage range of 2.3 V to 3.6 V and functions within a temperature range of -40°C to +85°C. The device utilizes a TQFP-EP-32 surface-mount package and communicates via a 4-Wire SPI interface. This component is designed for high-precision timing measurements in sensor applications.

Feature Summary

• Integrates a dedicated analog front end specifically optimized for time-to-digital conversion tasks.
• Supports standard serial communication protocols through a four-wire SPI interface for configuration and data retrieval.

Applications

• Ultrasonic flow meters
• Time-of-flight distance measurement systems
• Industrial sensor interfaces requiring precise timing

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging, distinct from the bulk or tray variants found in related part numbers. Confirm current lifecycle status as the base model MAX35101EHJ+ is listed as obsolete in some distributor records. Ensure compatibility with existing PCB footprints for the TQFP-EP-32 package before finalizing procurement orders.

Selection Notes

Select this component when a single-channel TDC with integrated signal conditioning is required. Compare against the MAX35103 if multiple channels are needed. Verify that the 2.3V to 3.6V operating voltage aligns with the system power rails. Ensure the design accommodates the thermal dissipation requirements of the exposed pad TQFP-EP-32 package.

Part Context

This part belongs to the MAX35101 series of time-to-digital converters. It serves as the integrated circuit counterpart to development tools like the MAX35101EVKIT. The device is positioned for applications demanding high-resolution temporal measurements without external timing components.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. The base model MAX35101EHJ+ is noted as obsolete; verify availability of alternative revisions or contact the manufacturer directly for obsolescence management strategies.
