Product details

MAX9892ERT+T: Shunt-Mode Audio Click-and-Pop Eliminator – 6-UCSP (CSPBGA), 1.7V to 3.6V
The MAX9892ERT+T from Analog Devices / Maxim Integrated is a shunt-mode audio click-and-pop eliminator designed for portable multimedia devices. It connects to the output of an existing amplifier and provides a low-impedance path to ground during startup/shutdown to suppress audible transients. It operates from a 1.7V to 3.6V supply, draws less than 1µA typical supply current, and is offered in a tiny 6-bump UCSP package.

Product Introduction

The MAX9892ERT+T is an audio transient suppression IC that targets the "click/pop" noise commonly heard in headphone and line outputs during power-up and power-down. It is used alongside an existing headphone amplifier or audio output stage.

During startup/shutdown, the MAX9892 provides a controlled shunt path that reduces audible artifacts while keeping distortion low. The part is designed for portable devices and supports operation from 1.7V to 3.6V with very low supply current.

It is available in extremely small packages, including a 6-bump UCSP, making it suitable for tight layouts in mobile/portable audio products.

Key Benefits

Click-and-Pop Suppression

Reduces startup/shutdown audio transients in portable devices.

Low Power Consumption

Designed for very low supply current to protect battery life.

Tiny UCSP Package

6-bump UCSP supports compact board layouts and slim products.

Works with Existing Amplifiers

Installs at amplifier outputs to improve user-perceived audio quality.

Technical Features

Shunt-Mode Elimination

Provides a low-impedance path during transitions to suppress audible artifacts.

Single-Supply Operation

Operates from 1.7V–3.6V in portable systems.

Portable Multimedia Focus

Built for phones, media players, notebooks and similar devices.

Equivalent & Manufacturer Information

Equivalent / Alternative Models

When replacing click/pop suppressors, compare: connection topology (shunt vs series), control pins/logic, acceptable audio swing, and package constraints.

  • MAX9890 family click/pop suppressors (verify topology and pin control)
  • Other ADI/Maxim depop solutions in UCSP/µDFN packages (space-driven selection)
  • System-level alternatives (amp with integrated pop/click suppression) if redesign is allowed
About the Manufacturer – Analog Devices / Maxim Integrated

Analog Devices (ADI), including the former Maxim Integrated portfolio, supplies high-performance analog, mixed-signal and power solutions used in consumer, industrial and communications markets. In portable audio designs, ADI/Maxim parts are commonly selected for compact integration and user-perceived performance improvements such as click-and-pop reduction.

Application Field

Mobile Phones

Headphone/line outputs with reduced startup/shutdown artifacts.

Portable Media Players

Improved user-perceived audio transitions.

Portable Gaming

Cleaner audio output during power-state changes.

Notebook Audio

Pop/click suppression in compact audio sections.

Quality Control

Incoming & Traceability

Lot/date code traceability with packaging integrity checks.

UCSP Handling

Strict ESD control and careful packing inspection for tiny bump packages.

Sampling Verification

Optional electrical sampling to confirm functional behavior in the audio path.

Pre-shipment Check

Final PN/qty verification to avoid mixing similar UCSP parts.

Frequently Asked Questions (FAQ)

1) What does MAX9892ERT+T do?
It suppresses audible click-and-pop during amplifier startup/shutdown using a shunt-mode approach.
2) Can it replace output capacitors?
It mainly targets transients; whether coupling capacitors are needed depends on your amplifier/output bias scheme.
3) What supply does it use?
It operates from 1.7V to 3.6V single-supply for portable devices.

Disclaimer

Audio transient behavior depends on the complete signal chain (amplifier, load, sequencing and PCB layout). Always validate click/pop performance on the final system and confirm limits in the official datasheet.
