UTC TA8227P LINEAR INTEGRATED CIRCUIT LOW FREQUENCY POWER AMPLIFIER DESCRIPTION The UTC 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, space merit is remarkable. Thermal shut down protection circuit is built in. FEATURES *Wide operating supply voltage: Vcc=5~12V *Low popping noise at power ON *Best for supply voltage 9V *Output power Po=2.5W/CH at Vcc=9V, RL=4Ω, f=1kHz, THD=10% Po=3.0W/CH at Vcc=9V, RL=3Ω, f=1kHz, THD=10% *Soft Clip *Built-in Thermal shut-down protection circuit *Stand-by Switch DIP-12H BLOCK DIAGRAM UTC UNISONIC TECHNOLOGIES CO., LTD. 1 QW-R107-011,B UTC TA8227P 1. Adjustment of voltage gain LINEAR INTEGRATED CIRCUIT APPLICATION INFORMATION AND APPLICATION METHOD The voltage gain Gv is obtained as follows by R1, R2 and Rf in Fig.1 When Rf=0Ω When Rf=120Ω Gv=56.5 dB (Typ.) Gv=45 dB (Typ.) By increas [ … ]
