Slew Rate
------------------------------------------------------------------------------------------------
Slew Rate = ΔV/Δt
STA540 Slew Rate = 16V / 7us = 2.26 V/us
TDA7297 Slew Rate = 16V / 3.5us = 4.57 V/us
TDA7266 Slew Rate = 16V / 5us = 3.20 V/us
* 量測環境: Supply Voltage: 19.3V
Room Temperature: 28 ˚C
