TA8229

UTC TA8229 LINEAR INTEGRATED CIRCUIT LOW FREQUENCY POWER AMPLIFIER DESCRIPTION The UTC TA8229 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 SIP (Single Inline Package), space merit is remarkable. Thermal shut down protection circuit is buit in. HSIP-15 FEATURES * High Power : Pout (1) = 2.5W (Typ.) (VCC = 9V, RL = 4Ω, f = 1kHz, THD = 10%) : Pout (2) = 4.6W (Typ.) (VCC = 12V, RL = 4Ω, f = 1kHz, THD = 10%) * Low Popping Noise at Power ON * Small Quiescent Current : ICCQ = 21mA (Typ.) (VCC = 15V, Vin = 0) * Soft Clip * Built-in Thermal Shut Down Protection Circuit * Best for Supply Voltage 9V, 12V * Operation Supply Voltage Range : VCC (opr) = 6 ~ 15V (Ta = 25℃) HSIP-14 PIN DESCRIPTION HSIP-14 1 2 3 4 5 6 7 8 9 10 11 12 13 14 PIN NO.
