EUA6011A is a stereo audio power amplifier from Texas Instruments that can output 3 watts of continuous RMS power and supports BTL (speaker) and SE (headphone) volume control.
The EUA6011A stereo audio power amplifier delivers up to 3 W continuous RMS power per channel into a 3 Ω load. It features advanced DC volume control with 2‑dB steps from –40 dB to +20 dB, a fade mode, and selectable BTL (speaker) or SE (headphone) output configurations. The device operates from a 4 V to 5.5 V supply and is RoHS compliant.
The datasheet provides pin configurations for the TSSOP‑24 package, absolute maximum ratings, electrical characteristics, typical application circuits, and thermal‑pad design guidelines. Recommended decoupling, bypass, and output‑coupling capacitors are listed to achieve low distortion and noise performance.
| Continuous output power | 3 W per channel into 3 Ω load |
|---|---|
| Supply voltage range | 4 V – 5.5 V |
| Total harmonic distortion (THD) | ≤1 % at 1 kHz |
| Volume control steps | 2 dB steps from –40 dB to +20 dB |
It can deliver 3 W per channel into a 3 Ω load.
Volume is set by applying a DC voltage to the VOLUME terminal; SE volume is limited by the SEMAX terminal.
Yes, the BTLSE/ terminal selects BTL or SE mode, allowing the same chip to drive speakers or headphones.
