Dual Audio Power Amplifier

The TB2922HQ is 2ch BTL audio amplifier for TV or home audio applications.
It includes and the pure complementary P-ch and N-ch DMOS output stage.
The package is CPP (Compact Power Package).
It is built-in standby function, muting function various kinds of protectors.

Features
• High power output
   : POUT (1)= 22 W (typ)
      (VCC = 18V, RL = 8 Ω, f = 1 kHz, THD = 10%)
   : POUT (2)= 37W (typ)
      (VCC = 16V, RL = 4 Ω, f = 1 kHz, THD = 10%)
   : POUT (3)= 46W (typ)
      (VCC = 26V, RL = 8 Ω, f = 1 kHz, THD = 10%)
   : POUTMAX (1)= 72W (typ)
      (VCC = 26V, RL = 8 Ω, f = 1 kHz, M ax Power)
• Low distortion ratio : THD=0.02% (typ)
• Low noise : Vno = 0.16 μ Vrms (typ)
   (VCC = 18V, RL = 8 Ω, Rg = 0 Ω, BW = 20 Hz~20 kHz)
• 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)
