DESCRIPTION

· The CS6A4689 is a stereo audio power amplifier designed for high-fidelity audio amplification with minimal external components.

· It operates in current-driven Class A mode, ensuring high-quality audio output without cross-over distortion.

· Recommended operating voltage is ±9V for optimal performance and stability, with a maximum of ±11V.

· Capable of delivering up to 2Wrms on a 16Ω headphone in a capacitor-less push-pull topology.

· Features a double current feedback sensing circuit for efficient current output and minimal power dissipation.

· Requires only a small heat sink or none at all, reducing product size and cost.

FEATURES

· Output capacitor-less push-pull topology.

· Integrated high-current output MOSFETs.

· Output impedance of 1Ω (typical).

· Two stereo output channels.

· External compensation β feedback circuit for tonal and offset adjustment.

· Current-driven Class A operation with IQ = 16mA (typical).

· High operating voltage of ±11V (max), ±9V (recommended).

· Embedded output load adaptation for 2Ω ≤ RL (2Ω recommended for low VDD).

APPLICATIONS

· Professional audio systems.

· Headphone amplifiers.

AVAILABLE PACKAGE

· SIP-10 package.
