Description

The TPA6040A4RHBR belongs to TPA6040A4 family. The TPA6040A4 is a stereo audio power amplifier and DirectPathTM headphone amplifier in a thermally enhanced, space-saving, 32-pin QFN package. The speaker amplifier is capable of driving 2 per channel continuously into 4-9 loads at 5 V. The headphone amplifier achieves a minimum of 85 mW at 1% THD+N from a 5-V supply. A built-in internal 4-step gain control for the speaker amplifier and a fixed -1.5 VN gain for the headphone amplifier minimizes external components needed. Independent shutdown control and dedicated inputs for the speaker and headphone allow the TPA6040A4 to simultaneously drive both headphones and internal speakers. Differential inputs to the speaker amplifiers offer superior power-supply and common-mode noise rejection.

The features of TPA6040A4RHBR are (1)microsoft™windows vista™ compliant; (2)fully differential architecture and high PSRR provide excellent rf rectification immunity; (3)2-W, 10% THD+N into 4- speakers and 85-mW, 1% THD+N Into 16- headphones headphone amplifier achieves a minimum of 85 mW from 5-V supply; (4)directpath™ headphone amplifier eliminates output capacitors (1: US patent number 5289137); (5)internal 4-step speaker gain control: 6, 10, 15.6, 21.6 db and fixed 1.5-V/V headphone; (6)independent shutdown controls for speaker, headphones and internal speakers. differential inputs headphone amplifier, and low dropout regulator (LDO); (7)4.75-V low dropout regulator for CODEC; (8)output short-circuit and thermal protection. The TPA6040A4RHBR can be used in notebook computers; portable DVD.
