Features
| A high efficiency of 91% (10W + 10W output with 8Ω load), which is the highest grade in the industry and low heat-generation. |
| An output of 20W + 20W (17V, with 8Ω load) is allowed without an external heat radiator. |
| Driving a lowest rating load of 3.6Ω is allowed. |
| Pop noise upon turning power on/off and power interruption has been reduced. |
| High-quality audio muting is implemented by soft-switching technology. |
| An output power limiter function limits excessive output to speakers. |
| High-reliability design provided with built-in protection circuits against high temperatures, against VCC shorting and GND shorting, against reduced-voltage, and against applying DC voltage to speaker. |
| 8) A master/slave function allowing synchronization of multiple devices reduces beat noises. |
| 9) Adjustment of internal PWM sampling clock frequencies (350kHz to 500kHz) allows easy protective measures against unwanted radio emission to AM radio band. |
| 10) A compact back-surface heat radiation type power package is employed. |
| HTSSOP-A44 (5mm × 7.5mm × 1.0mm, pitch 0.8mm) |
