34119-HLF-2V to 16V Low Power Audio Amplifier IC

HLF34119 is a low-power audio amplification integrated circuit. This circuit is suitable for low-power audio amplifiers on telephones (such as speaker phones). It can drive the speaker with maximum differential output under low power supply voltage conditions (minimum 2V) without the need for coupling capacitors. The open-loop gain can reach 80dB, and the closed-loop gain can be set through two external resistors. There is a chip input terminal inside that causes the input signal to power down or silence the input signal. The circuit can be connected to applications such as high input impedance audio amplification, low frequency compressed audio amplification, band-pass audio amplification, and dual power operation audio amplification. Adopting DIP8 and SOP8 packaging forms. Images for reference only.
