1 The output power of the SPA1010 is limited by frequency. When the input frequency is between 500 Hz and 200 kHz, the SPA1010 is able to deliver 10 watts into an 8 Ω load. As the SPA10100 has an overload protection circuit and a thermal protection circuit to prevent permanent damage, it will not deliver 10 watts when the input frequency is below 500 Hz and above 200 kHz.
2 The full power bandwidth refers to the maximum frequency of the signal generated with undistorted and utmost amplitude in the AC output state from the Amplifier.
FPB = SR / (2πVMAX)
SR: Slew Rate; VMAX: Maximum undistorted output amplitude
3 Slew Rate: When you send a large step signal to the amplifier, the output slope of the signal will be stable as a constant at a certain point; this constant is named Slew Rate.
