Max9890bebl T

The MAX9890BEBL+T is a specialized audio click-pop suppressor integrated circuit (IC) primarily used in portable consumer electronics like smartphones and tablet PCs MouserHotenda. Developed by Maxim Integrated (now part of Analog Devices), it is currently entering a phase of restricted availability and is Not Recommended for New Designs (NRND) as of 2026 MouserDigikey.

Technical Overview

This IC is designed to eliminate audible transients (clicks and pops) during the power-up and power-down cycles of audio amplifiers.

* Key Specs: Operates between 2.7V to 5.5V with an ultra-low quiescent current of ~10µA MouserHotenda.

* Version Difference: The "B" version (MAX9890BEBL) features a 330ms turn-on time compared to the 200ms of the "A" version Omo-Ic.

* Package: It uses a compact 9-bump UCSP™ (Ultra Chip-Scale Package), making it ideal for high-density mobile PCBs AlibabaDigikey.

Market Trends & Insights

* Supply Chain Status: Major authorized distributors like Mouser and DigiKey have flagged the item for restricted availability, indicating that stock is no longer being replenished through standard channels MouserDigikey.

* Procurement Shift: Current market demand is shifting toward spot inventory and specialized B2B sourcing in regions like Shenzhen and Hong Kong YidongNtchip. Pricing from these suppliers typically ranges from $0.69 to $1.82 per piece, depending on the order volume and stock age AlibabaAlibaba.

* Competitive Landscape: As this specific model nears end-of-life (EOL), designers are pivoting toward integrated audio codecs that include built-in click-pop suppression, or newer ICs with smaller footprints and lower THD+N SnapedaAnalog.

Strategic Recommendations

1. 1For Current Production: Secure existing stock immediately from verified B2B distributors in Shenzhen or HK, as primary distribution channels are closing HardfindelecUtsource.
2. 2For Maintenance/Repair: The MAX9890BETA+T serves as a functional equivalent but uses an 8-TDFN package instead of the 9-UCSP, requiring PCB layout modifications EiyuOmo-Ic.
3. 3Future Development: Transition to active-lifecycle audio solutions to avoid supply chain risks associated with restricted parts.
