The Headphone AMP 3 Click Board™ is a compact add-on board with a stereo amplifier. This board features the INA1620, a high-fidelity audio operational amplifier with integrated thin-film resistors and EMI filters from Texas Instruments. Over its dual amplifiers, it achieves a very low noise density and drives a 32Ω load at 150mW of output power. Total harmonic distortion plus noise (THD+N), a degree to which an amplifier alters a pure sinusoidal signal by adding harmonics to the fundamental signal, is ultra-low, some -119.2dB at 1KHz. This Click board™ makes the perfect solution for developing high-fidelity (Hi-Fi) headphone drivers, professional audio equipment, audio test, measurement devices, analogue and digital mixing consoles, and more.
The Headphone AMP 3 Click Board™ is supported by a mikroSDK-compliant library, which includes functions that simplify software development. This Click board™ is a fully tested product, ready for use on a system equipped with the mikroBUS™ socket.
