The TPA6030A4 is designed to drive 3 W into 16- speakers using a surface-mount package without the need for an external heatsink. These features make it ideal for 15" 17" LCD monitors, small multimedia speakers, and notebook computers.
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 sinksminimizing solution cost and size.
