UNISONIC TECHNOLOGIES CO., LTD PA5417
HIGH-OUTPUT DUAL POWER AMPLIFIER
DESCRIPTION
The UTC PA5417 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.
LINEAR INTEGRATED CIRCUIT
HZIP-15A
FEATURES
* Operating power supply voltage range from 6V to 15V. * High output. - POUT = 2.8W (VCC = 9V, RL=3, THD = 10%) - POUT = 5.0W (VCC = 12V, RL=3, THD = 10%) * Excellent audio quality - THD = 0.1% (f = 1kHz, POUT = 0.5W) - eN = 0.3mVrms (Rg = 10k) - 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: PA5417L
