Texas Instruments,12W, 24-Pin HTSSOP TPA3001D1PWP

A range of highly integrated Class-D Audio Power Amplifier ICs from Texas Instruments providing high efficiency and compact dimensions. The devices are suitable for a wide variety of uses including stereo audio equipment, automotive applications, television, PDA, computer and mobile applications.

The Texas Instruments TPA3001D1 is a 20-W monaural bridge-tied load (BTL) class-D audio power amplifier (class-D amp) with high efficiency, eliminating the need for heat sinks. The device can drive 4- or 8- speakers with only a ferrite bead filter required to reduce EMI. The gain of the amplifier is controlled by two input terminals, GAIN1 and GAIN0. This allows the amplifier to be configured for a gain of 12, 18, 23.6, or 36 dB. The differential input stage provides high common-mode rejection and improved power-supply rejection.
