Texas Instruments TAS5132DDV2EVM
The TAS5132DDV2EVM is composed of two separate modules, the HPL-MC012 Modulator/Controller Module and the TAS5132DDV2EVM Amplifier Module. They are designed so that the user can separate the two modules and connect the TAS5132DDV2EVM Amplifier Module in to a target system via a ribbon cable. Keep this ribbon cable as short as possible to avoid degradation in the PWM signals. The TAS5132DDV2EVM PurePath Digital™ customer evaluation amplifier module demonstrates two audio integrated circuits - the TAS5086 and the TAS5132 from Texas Instruments (TI). The TAS5086DBT is a high-performance, 32-bit (24-bit input), multichannel PurePath Digital™ pulse width modulator (PWM) based on Equibit™ technology with fully symmetrical AD modulation scheme. It accepts an input sample rate from 32 kHz to 192 kHz. The device also has digital audio processing (DAP) that provides bass management, advanced performance, and a high level of system integration. The TAS5132DDV is a compact, high-power, digital amplifier power stage designed to drive an 8ω loudspeaker up to 20 W/10% THD+N. It contains integrated gate-drive, four matched and electrically isolated enhancement-mode N-channel power DMOS transistors, and protection/fault-reporting circuitry. The DDV package has a PowerPAD™ package on the top side for heat transfer through a heat sink. The heat sink in this design is for evaluation purposes only. This EVM plus the HPLMC-012 is a complete 2-channel, digital audio amplifier system which includes digital input (S/PDIF), control interface (via USB) to PC and DAP features like digital volume control, bass management, and input and output multiplexers. This EVM is designed to illustrate a low-cost approach to an amplifier design using this device. Improved performance, at increased cost, can be achieved with a high-performance configuration.
