FAN3850TUC15X35

Overview

The FAN3850TUC15X35 is a mono audio amplifier manufactured by onsemi, formerly Fairchild Semiconductor. It operates as a Class AB amplifier designed for low-voltage applications. The device features an integrated analog-to-digital converter (ADC) and supports microphone input capabilities. It is housed in a compact 6-WLCSP package with dimensions of 1.26x0.86 mm. The operational supply voltage range spans from 1.64V to 3.63V. The component is rated for an operating temperature range between -30°C and 85°C.

Feature Summary

Integrates Class AB amplification with digital output capabilities
Includes built-in ADC functionality for direct signal processing
Supports microphone pre-amplification inputs
Designed for ultra-compact surface-mount integration

Applications

Mobile phone audio subsystems
Portable media players
Voice recognition modules

Procurement Notes

Verify the manufacturer designation carefully, as the component was originally produced by Fairchild Semiconductor before its semiconductor division became onsemi. Confirm the specific suffix X35 matches the required 6-WLCSP packaging variant. Ensure the revision level aligns with current design specifications, as legacy documentation may reference Fairchild branding while current datasheets use onsemi identifiers.

Selection Notes

Select this component when a combined amplifier and ADC solution is required for space-constrained designs. The low supply voltage requirement suits battery-operated devices. Verify that the single-channel mono configuration meets the system's audio channel requirements. Ensure the WLCSP footprint fits within the available PCB area constraints.

Part Context

This part belongs to the FAN3850 family of audio components. Related variants include the FAN3850A and FAN3850TUC13X35. These devices share similar functional architectures but may differ in packaging or specific electrical characteristics. The family is designed for integrating microphone interfaces directly into digital audio paths without external conversion stages.

Replacement Considerations

The FAN3850TUC13X35 is a documented alternative within the same product family. Verify pin compatibility and electrical specifications before substitution. Other manufacturers offer I2S digital microphones, but these require different interface logic compared to the integrated amplifier-ADC architecture of this component.
