This information is based solely on the manufacturer's specifications for the STK4042.

Application Scenarios & Design Considerations

AF Power Amplifier (Split Power Supply) (80 W min, THD = 0.4%)

Alternative Part Number

  • LM3886TF --: Popular single-chip audio power amplifier in the same output power class with similar supply voltage range; well-documented and widely available replacement for STK-series hybrid modules.
  • TDA7294 --: DMOS audio power amplifier IC with comparable output power and supply requirements, commonly used as a substitute for Sanyo STK thick-film audio modules.
  • STK4044 --: Higher-power member of the same STK404x hybrid family with identical pinout and similar electrical characteristics, usable where slightly higher output capability is acceptable.
