Delivering a minimum of 60 Watts of continuous power, this module is engineered for audiophile-grade sound systems. By utilizing an internal current mirror and cascode circuit, the STK4038XI achieves an ultra-low Total Harmonic Distortion (THD) of just \u003cstrong\u003e0.008%\u003c\/strong\u003e.\u003c\/p\u003e\n\n\u003cp\u003eThis mono module is a critical replacement part for high-end center channel speakers, active studio monitors, and mono-block power amplifiers where sonic transparency and a silent noise floor are paramount.\u003c\/p\u003e\n\n\u003ch4\u003eKey Technical Features:\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContinuous Power Output:\u003c\/strong\u003e 60W Minimum (at 8Ω, 20Hz to 20kHz, THD = 0.008%).\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUltra-Low Distortion:\u003c\/strong\u003e 0.008% THD provides studio-quality, transparent audio reproduction.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInternal Architecture:\u003c\/strong\u003e Pure complementary circuit with cascode stages for superior linearity.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFrequency Response:\u003c\/strong\u003e 20Hz to 50kHz (+0, -3dB).\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperating Voltage:\u003c\/strong\u003e Recommended supply of ±40V (Absolute Maximum ±58V).\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePin Compatibility:\u003c\/strong\u003e Pin-compatible with the STK4036XI through STK4044XI series for flexible power scaling.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eInstallation \u0026amp; Thermal Care:\u003c\/h4\u003e\n\u003cp\u003eThe STK4038XI \u003cstrong\u003emust\u003c\/strong\u003e be securely mounted to a flat, clean heatsink using high-quality thermal grease. Because of its precision internal bonding, operating the module without a heatsink—even for a brief functional test—will cause immediate and permanent damage. Verify that your power supply rails are symmetrical and ideally near ±40V for optimal performance.\u003c\/p\u003e\n\n\u003cp\u003e\u003cem\u003eTechnician's Note: Before installing a new module, always inspect the output emitter resistors and protection circuitry. A failure in the original chip is often caused by external shorts that must be resolved to protect your new replacement.\u003c\/em\u003e\u003c\/p\u003e","brand":"Sanyo","offers":[{"title":"New","offer_id":48006075318426,"sku":"SC0007","price":29.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0555\/9477\/8778\/files\/35-STK4038XI_20Sanyo_20AF_20Power_20Amplifier.jpg?v=1778389472","url":"https:\/\/prellelectronics.com\/products\/stk4038xi-sanyo-audiophile-mono-amplifier-hybrid-ic-60w","provider":"Prell Electronics","version":"1.0","type":"link"}
