Audio Amplifiers TAS6422Q1EVM: 75W x 2 @ 4Ω, Digital Input, w/I2C Diagnostics, Class-D, 2.1Mhz Manufacturer: Texas Instruments

The TAS6422Q1EVM showcases the first true 2.1Mhz 2-Ch Digital Input Class-D Audio Solution for Automotive Infotainment in the market. TAS6422’s 2.1-Mhz switching frequency allows customers to significantly reduce inductor size and cost and optimize total system cost. TAS6422 delivers 25W (10% THD+N) per channel into 4-Ω with a 14.4-V supply.

Audio Amplifiers TPA3156D2EVM: 70W x 2 @ 4Ω, Class-D, Inductor Free Manufacturer: Texas Instruments

The TPA3156D2 has low idle power loss and helps to extend the battery life of Bluetooth/Wireless speakers and other battery-powered audio systems. The high efficiency of the TPA3156D2 device allows it to do 2 × 70 W with external heat sink on a dual layer PCB. This device integrates an efficiency boost mode, which dynamically reduces the current ripple of the external LC filter and the idle current.

Audio Amplifiers TAS2770EVM: Mono, 18.3W @ 4Ω, Digital Input, Class-D, IV Sense Audio Amplifier Manufacturer: Texas Instruments

The TAS2770EVM provides developers with a simple to use mono evaluation module that can be configured as a stereo solution and as a multi-channel solution. It is powerful tool kit for assessing stereo and mono implementations of the TAS2770 with or without IV sense. Everything needed for evaluating TAS2770 is provided. A stereo or mono speaker protection solution can be evaluated by connecting a TAS2559YZEVM to provide the speaker protection algorithm and processing.
