Additional Details:

The STK402-240 needs dual power supplies (+V and -V), typically ±30V to ±45V, depending on the specific design and desired power. The module accepts an analog audio signal for amplification. Internal biasing and compensation ensure stable operation. Key specifications include output power, THD, input impedance, gain, and SNR. Adequate heat sinking is necessary for heat dissipation. The internal protection circuits guard against damage. Always consult the datasheet provided by the manufacturer.
