Features

1. Supports circuit designs that do not require output LC filters
2. BTL output, class D amplifier system
3. Unique SANYO-developed feedback technology achieves superb audio quality
4. High-efficiency class D amplifier
5. Soft muting function reduces impulse noise at power on/off

Functions

1. 10W output (At VD = 12V, RL = 8Ω, THD + N = 10%)
2. 15W output (At VD = 12V, RL = 4Ω, THD + N = 10%)
3. Efficiency : 88% (VD = 12V, RL = 8Ω, fin = 1kHz, PO = 10W)
4. Low THD + N : 0.15% (VD = 12V, RL = 8Ω, fin = 1kHz, PO = 1W, Filter : AES17)
5. Noise : 100μVrms (Filter : A-weight)
