1 / 36 page  December 2008 Rev 1 1/36 36 TS4999 Filter-free stereo 2.8 W class D audio power amplifier with selectable 3D sound effects Features ■ Operates from VCC = 2.4 to 5.5 V ■ Dedicated standby mode active low/channel ■ Output power per channel: 2.8 W at 5 V into 4 Ωwith 10% THD+N or 0.7 W at 3.6 V into 8 Ω with 1% THD+N max. ■ Selectable 3D sound effect ■ Four gain setting steps: 3.5, 6, 9.5 and 12 dB ■ Low current consumption ■ PSSR: 63 dB typical at 217 Hz. ■ Fast start up phase: 7.8 ms ■ Short-circuit and thermal shutdown protection ■ Flip chip 18-bump lead-free package Applications ■ Cellular phones ■ PDAs ■ Notebook PCs Description The TS4999 is a stereo fully-differential class D power amplifier. It can drive up to 1.35 W into a 8 Ω load at 5 V per channel. The device has four different gain settings utilizing two discrete pins, G0 and G1. Pop and click reduction circuitry provides low on/off switch noise while allowing the device to start within 8 ms. 3D enhancement effects are selected through one digital input pin that allows more amazing stereo audio sound. Two standby pins (active low) allow each channel to be switched off separately. The TS4999 is available in a flip chip, 18-bump, lead-free package.
