Overview

MC34119 is a low-power audio amplifier IC. This circuit is designed for low-power audio amplification in telephone applications (e.g., speakerphones). It can drive a speaker in maximum differential output mode under low supply voltage conditions (as low as 2V), eliminating the need for coupling capacitors. Open-loop gain reaches up to 80dB, and closed-loop gain can be set via two external resistors. An on-chip input enable allows the input signal to be powered down or muted. The circuit can be configured for high input impedance audio amplification, bass compression audio amplification, bandpass audio amplification, and dual-supply audio amplification applications. Available in DIP-8, SOP-8, and MSOP-8 packages.

Key features

Wide supply voltage range (Vcc = 2V ~ 16V), allows powering directly from telephone line
Low quiescent supply current (typical 2.7mA), suitable for battery-powered applications
Chip disable input for power-down control
Low quiescent current in power-down mode (typical 65µA)
Wide speaker load range (≥8Ω)
Output power exceeds 250mW with 32Ω load
Low THD (typical 0.5%)
Audio gain adjustable from 0 ~ 46dB
Minimal external components
