Key Features
- 3.7W per channel stereo Class D amplifier with up to 90% efficiency — ideal for battery-powered portable speakers
- Fixed 18dB gain with 22kHz bandwidth delivers clear, full-range audio performance without external gain-setting resistors
- Ultra-compact 14-pin TQFN (3mm × 3mm × 0.75mm) package minimizes PCB footprint for space-constrained audio designs
- Filterless Class D architecture reduces BOM cost by eliminating LC output filter components while meeting FCC/CE EMI standards
Applications
The MAX98306ETD+T is designed for portable Bluetooth speakers, smartphone docking stations, and tablet audio output stages where high efficiency and compact size are critical. Its 3.7W stereo Class D output provides adequate acoustic power for handheld and desktop consumer audio products operating from a single 5V supply. The filterless architecture further reduces board area and component count, making it well-suited for cost-sensitive consumer electronics designs.

Frequently Asked Questions
How efficient is the MAX98306ETD+T Class D amplifier compared to a linear Class AB amplifier at the same output power?
The MAX98306ETD+T Class D amplifier achieves efficiency of up to 90% at 3.7W output into an 8Ω load, versus roughly 50% to 65% for a comparable Class AB design. This efficiency advantage translates directly to longer battery runtime in portable speakers and less heat dissipation, eliminating the need for heatsinks even at full 3.7W output.
Does the MAX98306ETD+T require an external LC filter at the speaker output?
No, the MAX98306ETD+T uses a filterless Class D topology that drives speakers directly without an LC reconstruction filter. This reduces the BOM by eliminating 2 inductors and 2 capacitors per channel — saving board space and cost — while still meeting FCC Class B and CE EMI requirements when used with short speaker cables of less than 1 meter.
Which portable audio platforms benefit most from integrating the MAX98306ETD+T?
Portable Bluetooth speakers, tablet audio subsystems, and wearable sound devices benefit most from the MAX98306ETD+T due to its stereo 3.7W output, single-supply 5V operation, and the 3mm × 3mm 14-pin TQFN footprint that fits easily on compact PCBs. Its 18dB fixed gain simplifies audio signal chain design without requiring gain-trim resistors.
What is the audio bandwidth of the MAX98306ETD+T and how does it support full-range speaker performance?
The MAX98306ETD+T provides a 22kHz audio bandwidth, covering the full human audible range from 20Hz to 20kHz with margin, ensuring that high-frequency audio content such as cymbal transients and speech consonants are faithfully reproduced without band-limiting at 3.7W stereo output power.
