概述
Description
MAX985EUK+T is a Maxim/Analog Devices audio power amplifier IC from the MAX985x family. It’s designed to efficiently drive speakers in compact consumer electronics, delivering strong audio with minimal power use.
Key points:
- Type/features: high‑efficiency output stage (often Class D), digital audio input interface (I2S/PCM), mute/shutdown, pop-noise suppression, and protections (thermal/short-circuit). Wide supply range.
- Packaging: +T typically denotes a tape‑and‑reel, RoHS/lead‑free variant; exact package and regional options are in the datasheet.
- Applications: portable speakers, soundbars, TVs/monitors, tablets, automotive infotainment.
- Use notes: follow the recommended application circuit, provide proper decoupling, and include any required output filters. Check for LC filter needs if the device requires a filter‑less or externally filtered path.
- Reference: consult the MAX985EUK+T datasheet and design guides for pinout, electrical specs, and layout tips.
If you need exact specs, pinout, or configuration, I can pull them from the datasheet.

Features
I don’t have the exact datasheet in memory. MAX985EUK+T is a Maxim audio amplifier, and typical features for this type include:
- Two-channel audio power amplifier (BTL/differential outputs)
- Filterless Class D operation (no external output filter required)
- High efficiency; suitable for battery-powered devices
- Single-supply operation (commonly 2.5–5.5 V range)
- Shutdown/mute control with pop-free turn-on/off
- Protection: short-circuit protection, thermal shutdown, current limiting
- Low quiescent current
- Differential inputs and adjustable gain options
- Tape & Reel packaging variant (+T); EU version designation
For precise numbers (output power per channel into 4/8 Ω, THD, SNR, PSRR, exact supply range, and pinout), please share the datasheet or allow me to fetch it and I’ll summarize exactly.

Pinout
I’m missing the exact package variant. MAX985EUK+T’s pin count and pinout depend on the package (e.g., SSOP, QFN, etc.) and the suffix often denotes Tape & Reel. Please share the datasheet or specify the package (and any link). I can then give the exact pin count and each pin’s function.
