.ti. TPA6030A4 SLOS395B - DECEMBER 2002 - REVISED JANUARY 2005 3-W STEREO AUDIO POWER AMPLIFIER WITH ADVANCED DC VOLUME CONTROL Features D 3 W Into 16 Ω From 12-V Supply D Volume Control for Speakers (BTL) and Headphones (SE) D Differential Inputs D Depop Circuitry D 1 µA Shutdown Current D Surface-Mount Package APPLICATIONS D LCD Monitors and LCD TVs D Multimedia Speakers D Notebook puters DESCRIPTION The TPA6030A4 is designed to drive 3 W into 16-Ω speakers using a surface-mount package without the need for an external heatsink. These Features make it ideal for 15I- 17I LCD monitors, small multimedia speakers, and notebook puters. To simplify system design, the speaker volume level is adjusted by applying a dc voltage to the VOLUME terminal. The delta between speaker volume and headphone volume can be adjusted by applying a dc voltage to the SEDIFF terminal. To avoid an unexpected high volume level through the headphones, a third terminal, SEMAX, limits the headphone volume level when a dc voltage is applied. Integrated depop circuitry and the fully differential design minimize pops, clicks, and unwanted noise to provide a high level of audio performance. The device is available in a 28-pin TSSOP PowerPAD package. The PowerPAD package is designed to transfer heat into the ground plane, eliminating the need for external heat sinks- minimizing solution cost and size.
