Texas Instruments OPA1622EVM Op Amp Evaluation Module
Texas Instruments OPA1622EVM Op Amp Evaluation Module (EVM) is a hardware platform for evaluating the performance of the OPA1622 audio operational amplifier. On the evaluation module, each channel of the OPA1622 is configured as a difference amplifier that receives a differential input signal from an audio analyzer or audio DAC and outputs a single-ended signal. The Texas Instruments OPA1622EVM includes a headphone connector that allows users to hear the audio quality of the OPA1622 using the headphone(s) of their choice. With high linear output current of 80mArms, the OPA1622EVM can drive headphone loads of 8Ω, 16Ω, 32Ω, 300Ω, 600Ω and higher.
Features
- Eases design by providing a quick and straightforward way to evaluate the OPA1622
- The audio jack provided on the evaluation module allows for quick listening tests of the OPA1622
- Input connectors on the evaluation module provide an easy way to evaluate the OPA1622 using an audio analyzer or an audio DAC that will be used in an end product
- The evaluation module design allows access to the Enable pin of the OPA1622 to test for a "pop" and "click" noise while the OPA1622 is being enable and disabled
