Texas Instruments TAS5076
The TAS5076 is an innovative, cost-effective, high-performance 24-bit six-channel digital pulse-width modulator (PWM) based on Equibit technology. The TAS5076 is designed to drive up to six digital power devices to provide six channels of digital audio amplification. The digital power devices can be six conventional monolithic power stages (such as the TAS5110) or six discrete differential power stages using gate drivers and MOSFETs.FEATURES
