External Components
• The starting time, ts, can be varied by changing the value of the input capacitor. A value of 2.2µF is recommended. A
smaller value will result in a lower starting time, and a larger value, a higher starting time.
• The output capacitor should have a value of 470µF. A lower value will cause the low-frequency roll-off and low-power
characteristics to deteriorate.
• A value of 470µF is recommended for the power supply capacitor, although this can change according to the design
setup conditions.
• In dual mode, BTL IN (the channel 2 negative feedback connection) should be left floating.
BTL mode
• The output capacitors should have a value of 470µF. If these are omitted, a ‘‘popping’’ noise occurs. Also, any output
offset will cause a current to flow which could damage the load under quiescent DC conditions.
• The output capacitors can be replaced with a single 220µF bipolar capacitor. A larger value can cause switching noise
when power is applied to the device.
