UNISONIC TECHNOLOGIES CO., LTD BA5417 LINEAR INTEGRATED CIRCUIT HIGH-OUTPUT DUAL POWER AMPLIFIER DESCRIPTION The UTC BA5417 is a dual power amplifier of 6~15V-compatible for radio cassette/Mini compo players use. It is developed to equip with standby switching functions for excellent total harmonic distortion and other basic characteristics. HZIP-15A FEATURES * Operating power supply voltage range from 6V to 15V. * High output. - POUT = 2.8W (VCC = 9V, RL=3Ω, THD = 10%) - POUT = 5.0W (VCC = 12V, RL=3Ω, THD = 10%) * Excellent audio quality - THD = 0.1% (f = 1kHz, POUT = 0.5W) - eN = 0.3mVrms (Rg = 10kΩ) - RR = 55dB (fRR = 100Hz) * Switching noise (“pop” noise) generated when the power is switched on and off is small. * Ripple mixing when motor starts has been prevented. * Built-in thermal shutdown circuit. * Built-in standby switch that output is not influenced. * Soft clipping. *Pb-free plating product number: BA5417L ORDERING INFORMATION Order Number Normal Lead Free Plating BA5417-J15-A-T BA5417L-J15-A-T Package Packing HZIP-15A Tube BA5417L-J15-A-T (1) Packing Type (1) T: Tube (2) Package Type (2) J15-A: HZIP-15A (3) Lead Plating (3) L: Lead Free Plating, Blank: Pb/Sn www.unisonic.com.tw Copyright © 2005 Unisonic Technologies Co., Ltd 1 of 7 QW-R107-049,A BA5417 LINEAR INTEGRATED CIRCUIT BLOCK DIAGRAM thermal shutdown circuit + - + 30k 30k 30k 30k standby 45 bootstrap bootstrap 45 FILTER 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 (N.
