MAX1932ETC+TG035

Overview

The MAX1932ETC+TG035 is a digitally controlled APD bias supply IC designed for fiber optic networks. It generates a low-noise, high-voltage output to bias avalanche photodiodes in optical receivers. The device operates with an input voltage range of 2.7V to 5.5V and provides a single output adjustable from 4.5V upwards. It features 0.5% accuracy and includes safety mechanisms.

Feature Summary

• Digitally controlled operation for precise bias adjustment
• High accuracy of 0.5% for stable APD performance
• Integrated safety features for protected operation

Applications

• Fiber optic network receivers
• Avalanche photodiode (APD) biasing
• Optical communication systems

Procurement Notes

Verify the exact suffix 'TG035' against official Analog Devices documentation to confirm tape-and-reel packaging specifications. Ensure the component matches the active status listed for the MAX1932 family. Cross-reference the marking code AABV if physical inspection is required. Confirm RoHS compliance via the '+T' designation in official datasheets.

Selection Notes

Select this component for applications requiring precise, low-noise biasing of avalanche photodiodes in optical receivers. The digital control interface allows for easy integration with microcontrollers or DSPs. Consider the 2.7V to 5.5V input range compatibility with standard logic levels. The 12-TQFN package suits space-constrained designs.

Part Context

This part belongs to the MAX1932 family of power management ICs specialized for fiber optic applications. Manufactured by Maxim Integrated, now part of Analog Devices Inc., these components are designed to replace discrete bias solutions. The ETC suffix indicates the specific temperature grade and package type within the product line.

Replacement Considerations

Check for direct pin-to-pin replacements within the MAX1932 series. Verify that any substitute maintains the 0.5% accuracy and digital control interface requirements for your specific optical receiver design.
