Features - High power : Pout = 2.5 W/CH (typ.) (VCC = 9 V, RL = 4 Ω, f = 1 k Hz, THD = 10%) Weight: 1.4 g (typ.) : Pout = 3.0 W/CH (typ.) (VCC = 9 V, RL = 3 Ω, f = 1 k Hz, THD = 10%) - Voltage gain : Gv = 45.0d B (typ.) (Rf = 120 Ω, f = 1 k Hz) : Gv = 56.5d B (typ.) (Rf = 0 Ω, f = 1 k Hz) - Small quiescent current : ICCQ = 21 m A (typ.) (VCC = 9 V, Vin = 0) - Ripple rejection ratio : R.R. = - 52d B (typ.) (VCC = 9 V, fripple = 100 Hz, Rg = 600 Ω) - Cross Talk : C.T. = - 50d B (typ.) (VCC = 9 V, f = 1 k Hz, Rg = 600 Ω) - Output noise voltage : Vno = 0.3 m Vrms (typ.) (VCC = 9 V, Rg = 10 kΩ, BW = 20 Hz~20 k Hz) - Stand-by switch - Soft clip - Built-in thermal shut down protection circuit - Operation supply voltage range: VCC (opr) = 5~12 V (Ta = 25°C) - Low popping noise at power ON - Best for supply voltage 9 V TA8227P 2002-03-05 Block Diagram TA8227P Application Information and Application Method 1. Adjustment of voltage gain The voltage gain Gv is obtained as follows...
