HT82V739 1200mW Audio Power Amp with Shutdown Features · Operating voltage: 2.2V to 5.5V · Wide temperature operating range · High signal-to-noise ratio · Low power-on and chip enable or disable POP noise. · Low distortion · Low standby current · Large output voltage swing · Power off control · Low power consumption · Direct drive speaker · Output power 1200mW at 10% THD+N into 8W · 8-pin SOP package (VDD=5V) Applications · Applied for HT36 series, HT86 series and other Holtek products General Description HT82V739 is an integrated class AB mono speaker driver contained in a 8-pin SOP package. The HT82V739 is capable of delivering 1200mW output power to an 8W load with less than 10% (THD+N) from a 5V power supply. The very low standby current in shutdown mode contributes to the reduction of power consumption of battery-powered equipments.

However, the rising time depends on C1. (*see the application circuits) C E O U T P tR Capacitor tR 0.1mF 1mF 4.7mF 10mF 2.2V 15ms 30ms 90ms 185ms 3V 15ms 30ms 90ms 185ms 4V 15ms 30ms 90ms 185ms Voltage For battery based applications, power consumption is a key issue, therefore the amplifier should be turned off when in the standby state. In order to eliminate any speaker sound bursts while turning the amplifier on, the application circuit, which will incorporate a capacitance value of C1, should be adjusted in accordance with the speaker¢s audio frequency response. A greater value of C1 will improve the noise burst while turning on the amplifier. The recommended operation sequence is: Turn On: ²Aud In² signal standby (1/2 VDD) ® enable amplifier ® wait tR for amplifier ready ® ²Aud In² signal start Turn Off: ²Aud In² signal finish ® disable amplifier ® wait tR for amplifier off ® ²Aud In² signal off A u d In tR tR C E O U T If the application is not powered by batteries and there is no problem with amplifier On/Off issue, a capacitor value of 0.1mF for C1 is recommended.
