MC34119P Description

Short technical summary and product information.

The MC34119P is a low power audio amplifier integrated circuit from ON Semiconductor, specifically designed for telephone applications such as speakerphones. It features differential speaker outputs to maximize output swing even at low supply voltages, with a wide operating supply voltage range from 2.0 V to 16 VDC, making it suitable for telephone line powered applications.

This amplifier offers a low quiescent supply current of 2.7 mA typical, ideal for battery-powered devices. It includes a Chip Disable input for powering down the IC, with a low power-down quiescent current of 65 μA typical. The MC34119P can drive a wide range of speaker loads, including 8.0 Ω and up, and can deliver over 250 mW of output power with a 32 Ω speaker.

Key electrical characteristics include an open-loop gain of 80 dB and a closed-loop gain that is adjustable from less than 0 dB to over 46 dB for voice band applications, set by two external resistors. It exhibits low total harmonic distortion of 0.5% typical. The component requires few external components for operation and is available in an 8-pin DIP package suitable for through-hole mounting.

The MC34119P is intended for applications where efficient audio amplification is required within a compact and low-power design. Its features make it a versatile choice for voice communication systems.
