TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA8227P
Low Frequency Power Amplifier
TA8227P is an audio power IC with built-in two channels
developed for portable radio cassette tape recorder with power
ON/OFF switch.
Because of the parts reduction and DIP (Dual Inline Package),
space merit is remarkable.
Thermal shut down protection circuit is built in.
Features
High power
: Pout = 2.5 W/CH (typ.)
(VCC = 9 V, RL = 4 , f = 1 kHz, THD = 10%)
: Pout = 3.0 W/CH (typ.)
(VCC = 9 V, RL = 3 , f = 1 kHz, THD = 10%)
Voltage gain
: Gv = 45.0dB (typ.) (Rf = 120 , f = 1 kHz)
: Gv = 56.5dB (typ.) (Rf = 0 , f = 1 kHz)
Small quiescent current
: ICCQ = 21 mA (typ.) (VCC = 9 V, Vin = 0)
Ripple rejection ratio
: R.R. = 52dB (typ.) (VCC = 9 V, fripple = 100 Hz, Rg = 600 )
Cross Talk
: C.T. = 50dB (typ.) (VCC = 9 V, f = 1 kHz, Rg = 600 )
Output noise voltage
: Vno = 0.3 mVrms (typ.) (VCC = 9 V, Rg = 10 k, BW = 20 Hz~20 kHz)
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
Weight: 1.4 g (typ.)
