MAX98307ETE+T

MAX98307ETE+T is a mono, filterless Class-D audio amplifier from Maxim Integrated (now Analog Devices). It is designed for portable speakers and small audio systems, delivering efficient audio power without requiring external output filters.
Key points:
- Single-supply operation (typical 2.7–5.5 V) drive a 4–8 Ω loudspeaker in a bridge-tied load configuration.
- Differential input (IN+ and IN–) with a mute/shutdown control and built-in protections (short-circuit, over-temperature, undervoltage).
- High efficiency, low quiescent current, and no external LC filter required on the speaker output.
- Applications: mobile devices, wearables, portable speakers, IoT audio.
Suffix notes:
- ETE+T indicates a RoHS-compliant part in Tape & Reel packaging for automated assembly.
For exact electrical specs, pinout, and layout guidelines, consult the current MAX98307 data sheet and application notes.

I can’t fetch live cross‑reference data. To suggest accurate equivalents, tell me the MAX98307ETE+T’s required specs (output power, supply voltage, load impedance, mono/stereo, input type, package). With that I’ll list close substitutes from TI, ST, Analog Devices, etc.

Here are the key features of MAX98307ETE+T (Maxim/Analog Devices):
- Mono, high-efficiency Class D audio amplifier.
- Differential input with Bridge-Tied Load (BTL) outputs for direct speaker drive.
- Filterless operation: no external output filter required in most applications.
- Built-in pop-noise suppression and soft-start on power-up/down.
- Wide single-supply operation with low quiescent current in idle.
- Protection features: overcurrent/shock protection, short-circuit to GND or V+, undervoltage lockout, thermal shutdown.
- Simple 1-supply system approach; compact package option.
- Packaging: Tape-and-reel variant available (suffix +T) for automated assembly.
Note: Exact electrical specs (supply voltage range, output power, efficiency) vary by variant; consult the datasheet for precise numbers.

- Pin count: 8 (MSOP-8/TSSOP-8 in MAX98307ETE+T package)
- Function: Mono, bridge-tied load (BTL) Class-D audio power amplifier. Uses a single supply, accepts differential input (IN+ / IN−), provides differential outputs (OUT+ / OUT−) to drive a speaker, and includes a shutdown/enable control pin (SHDN). No external output filter required.

Manufacturer: Maxim Integrated (the MAX98307ETE+T is a Maxim part). Maxim Integrated was acquired by Analog Devices in 2021, so the product now falls under Analog Devices' portfolio.
What kind of company: Maxim Integrated (now part of Analog Devices) is an American semiconductor company that designs and manufactures analog and mixed-signal integrated circuits—power management, signal conditioning, data converters, and audio ICs—for industrial, automotive, communications, and consumer electronics markets.

MAX98307ETE+T is a compact, high-efficiency stereo Class-D audio amplifier. Typical app areas include:
- Portable Bluetooth speakers and mini-speakers
- Smartphones/tablet accessories and USB DACs
- PCs, game consoles, and multimedia dongles
- Home entertainment devices (soundbars, TV audio adapters)
- Smart home/voice assistants and conferencing devices
- Embedded consumer electronics needing low-heat, power-efficient 3W-class audio amplification
