Features - : : : : - - - - - - - High power output POUT (1)= 22 W (typ) (VCC = 18V, RL = 8 Ω, f = 1 k Hz, THD = 10%) POUT (2)= 37W (typ) (VCC = 16V, RL = 4 Ω, f = 1 k Hz, THD = 10%) POUT (3)= 46W (typ) (VCC = 26V, RL = 8 Ω, f = 1 k Hz, THD = 10%) POUTMAX (1)= 72W (typ) (VCC = 26V, RL = 8 Ω, f = 1 k Hz, Ｍax Power) Low distortion ratio Low noise : THD=0.02％ (typ) : Vno = 0.16 μVrms (typ) (VCC = 18V, RL = 8 Ω, Rg = 0 Ω, BW = 20 Hz~20 k Hz) Low outside parts Built-in standby switch function (pin 1) Built-in muting function (pin 6) Built-in various protection circuits: Thermal shut down, overvoltage, out to GND, out to VCC, out to out short speaker burned Operating supply voltage : VCC (opr) = 9 to 26 V (RL = 8 Ω) : VCC (opr) = 9 to 18 V (RL = 4 Ω) Note 1: Install the device correctly. Otherwise, the device or system may be degraded, damaged or even destroyed. Note 2: The protection features are intended to avoid output short-circuits or other abnormal conditions temporarily. It is not guaranteed that they will prevent the IC from being damaged. Exposure to conditions beyond the guaranteed operating ranges may not activate the protection features , resulting in an IC damage due to output short-circuits. Note 3: If HBM ESD(condition; 100p F/1.5kΩ) of under -1900V is applied to pin 2 or pin 4 in case that pin3 is GND, this product may break down. 2007-02-20 Block Diagram C5 7 VCC2 OUT1 (+) 4 IN1 8 ..

C3 RL 2007-02-20 Caution and Application Method (Description is made only on the single channel) 1. Voltage Gain Adjustment This IC has no NF (negative feedback) Pins. Therefore, the voltage gain can not be adjusted, but it makes the device a space and total costs saver. Amp. 2A...
