特性 Features

• High power output

: POUT MAX (1) = 41 W (typ.)

(VCC = 14.4 V, f = 1 kHz, JEITA max, RL = 4 Ω)

: POUT MAX (2) = 37 W (typ.)

(VCC = 13.7 V, f = 1 kHz, JEITA max, RL = 4 Ω)

: POUT MAX (3) = 70 W (typ.)

(VCC = 14.4 V, f = 1 kHz, JEITA max, RL = 2 Ω)

: POUT (1) = 27 W (typ.)

(VCC = 14.4 V, f = 1 kHz, THD = 10, RL = 4 Ω)

: POUT (2) = 23 W (typ.)

(VCC = 13.2 V, f = 1 kHz, THD = 10, RL = 4 Ω)

: POUT (3) = 46 W (typ.)

(VCC = 14.4 V, f = 1 kHz, THD = 10, RL = 2 Ω)

• Low distortion ratio: THD = 0.015 (typ.)

(VCC = 13.2 V, f = 1 kHz, POUT = 5 W, RL = 4 Ω)

• Low noise: VNO = 90 μVrms (typ.)

(VCC = 13.2 V, Rg = 0 Ω, BW = 20 Hz to 20 kHz, RL = 4 Ω)

• Built in stand by & muting function: controlled via I2C Bus (pin 16)

• Built in clipping detection (pin 4)

• Built in I2C Bus for stand-by, mute, voltage gain control, self diagnosis: Output short detection, offset detection,

tweeter or speaker open detection (pin 22 and 25)

• Built-in various protection circuits (Note 1, Note 2)

Thermal shut down, over-voltage, out to GND, out to VCC, out to out short circuit

• Operating supply voltage: VCC (opr) = 9 to 18 V (RL = 4 Ω)

VCC (opr) = 9 to 16 V (RL = 2 Ω)
