MAX98307ETE+T

MAX98307ETE+T is Maxim’s mono, filterless Class D audio power amplifier in an ETE package (tape and reel available). It provides a high‑efficiency, single‑channel audio amp that can drive a speaker directly from a battery or low-voltage supply, with no external output filter required.
Key points:
- Mono, bridge-tied load (OUT+ and OUT−) directly to a speaker.
- Input: IN+ (and IN− for differential operation); SHDN for standby/mute.
- Supply: operates from a low-voltage supply (typical battery rail); includes protections (short‑circuit, thermal) and pop/noise suppression on power‑up.
- Features: high efficiency, small footprint, suitable for portable devices (Bluetooth speakers, handhelds, wearables, etc.).
- Package: small ETE package; +T denotes tape-and-reel packaging.
How to use (overview):
- Connect VDD to your supply, GND to ground.
- Feed audio into IN+ (IN− can be tied to GND or used for differential input).
- Connect speaker between OUT+ and OUT−.
- Use SHDN to enable/disable the device; add proper decoupling and layout to minimize EMI.
- See the datasheet for exact electrical specs and application notes.
If you need exact voltage ranges, quiescent current, or protection thresholds, consult the MAX98307 datasheet.

Key features of MAX98307ETE+T (class-D audio amplifier)
- Stereo, filterless Class-D audio amplifier for portable applications
- High efficiency with low quiescent current
- Operates from a low-voltage single supply (typical range 2.7–5.5V)
- Differential inputs with mute/standby control; pop-free on power-up
- Integrated protection: overcurrent, short-circuit, and thermal shutdown
- Speaker protection and fault indicators (where supported)
- No external LC filter required for most loads; PWM outputs drive 4–8Ω loads
- Compact packaging with ETE+T (Tape & Reel) options
- Suitable for battery-powered devices and consumer audio products
Note: For exact electrical specs, load compatibility, and package details, consult the MAX98307 datasheet and the specific ETE+T variant documentation.

MAX98307ETE+T uses a 16‑pin TQFN package (4.0 x 4.0 mm) with an exposed pad; tape‑and‑reel (T) packaging option.

- Pin count: 28 pins (QFN/leadframe package, with exposed pad).
- Function: Dual-channel, high-efficiency Class-D audio power amplifier (stereo) suitable for driving speakers; supports differential inputs and PWM outputs, with typical protection features (mute, thermal/UVLO).

Manufacturer: Analog Devices, Inc. (Maxim Integrated brand).
Type of company: A multinational semiconductor company that designs and manufactures analog, mixed-signal, and DSP integrated circuits.

MAX98307ETE+T is a high-efficiency Class-D audio amplifier with digital input used to drive small loudspeakers. Ideal applications include Bluetooth portable speakers and other portable consumer audio devices, embedded multimedia gear (TVs, soundbars, game consoles), USB/docked audio adapters, smart speakers and IoT voice devices, and automotive infotainment systems needing compact, low-heat speaker amplification.
