DBL1034A Stereo Audio Amplifier IC

DBL1034A Stereo Audio Amplifier IC

The DBL1034A is a dual-channel stereo audio amplifier IC housed in a compact DIP-12 package. Designed for low-power, high-fidelity applications, it delivers two independent output channels of up to 3 W each into 4 Ω speakers. Its internal architecture integrates biasing and thermal-shutdown circuitry, minimizing the number of external components required for a complete amplifier stage.

At its core, the DBL1034A employs a complementary-symmetry push-pull (class-AB) output stage that ensures low crossover distortion and efficient power delivery. The device includes built-in protection against thermal overload and short-circuit conditions. Inputs are differential, allowing easy coupling to preamplifier stages with AC-coupling capacitors, while the outputs can be configured in either single-ended or bridged-mode for higher voltage swing.

Features:

• Dual independent stereo outputs.
