The INA1620EVM is a hardware platform for evaluating the INA1620 audio operational amplifier. Each channel of the INA1620 is configured as a difference amplifier, allowing easy connection to an audio analyzer or audio DAC, and outputs a single-ended signal. The INA1620EVM includes a headphone output to allow users to hear the audio quality of the INA1620 using the headphones of their choice. The INA1620EVM also provides the ability to utilize the INA1620's internal thin-film resistors for other applications.

Features:

• Eases design by providing a quick and simple way to evaluate the INA1620
• Audio jack provided on the EVM allows for quick listening tests of the INA1620
• Differential input connectors provide an easy way to evaluate the INA1620 using an audio analyzer or an audio DAC to be used in the end product
• Provides access to the INA1620's Enable pin for evaluation of "pop" and "click" performance during enable and disable
• Provides access to the INA1620's internal matched thin-film resistors.

The TAS2555YZEVM evaluation module provides users with an small reference board for complete evaluation of the TAS2555 Audio Amplifier. Shipped complete with a reference speaker, users can quickly hear the audio quality of the TAS2555 solution or start developing on their own speaker/application. The board provides an USB connection to your PC and is controlled by our PurePath Console 3 (PPC3) software suite where you can further fine-tune the solution to your liking.  Connect two EVMs together and the solution quickly transforms into a stereo solution.

The EVM also includes a connection to the Smart Amplifier Learning Board v2 where additional speakers can be characterized for your application while using the advanced features of PPC3.

Features:

• TAS2555 5.7W Class-D Audio Amplifier w/ IV Sense
• Reference speaker
• USB cable
• Access to TAS2555 App for PurePath Console 3

The TAS2770EVM-Stereo evaluation module provides developers with a simple to use module pre-configured in as a stereo solution. It is powerful tool kit for assessing stereo or mono implementations of the TAS2770 with or without IV sense. Everything needed for evaluating TAS2770 as a conventional amp is provided. A stereo or mono speaker protection solution can be evaluated by connecting a TAS2559YZEVM to provide the speaker protection algorithm and processing. The algorithm is controlled and tuned using PPC3. The TAS2559YZEVM and PPC3 add-in are not included and must be ordered separately.

Features:

• Stereo or Mono evaluation mode
• USB input
• IV sense evaluation mode
• Interface to TAS2559YZEVM for speaker protection evaluation
• Access to TAS2770 add-in PurePath Console 3
