TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA8223K
Low Frequency Power Amplifier
TA8223K is an audio power IC with built-in two channels
developed for portable radio cassette tape recorder with power
ON/OFF switch. Thermal shut down protection circuit is built in.
Features
· High power
: Pout (1) = 6.5 W (typ.)
(VCC = 15 V, RL = 4 Ω, f = 1 kHz, THD = 10%)
Pout (2) = 7.3 W (typ.)
(VCC = 15 V, RL = 3 Ω, f = 1 kHz, THD = 10%)
· Low popping noise at power ON
· Small quiescent current
: ICCQ = 29 mA (typ.) (VCC = 15 V, Vin = 0)
· Soft clip
· Built-in thermal shut down protection circuit
· Operation supply voltage range: VCC (opr) = 6~18 V (Ta = 25°C)
Weight: 3.9 g (typ.)
