Audio Switching Amplifier AD1994 Features Integrated stereo modulator and power stage <0.005% THD + N 105 dB dynamic range (A-weighted) 2 × 25 W output power (6 Ω, 10% THD + N) 1 × 50 W output power (3 Ω, 10% THD + N) RDS-ON < 0.3 Ω (per transistor) PSRR > 65 dB On-off-mute pop noise suppression EMI optimized modulator Short-circuit protection Overtemperature protection Low cost DMOS process GENERAL DESCRIPTION The AD1994 is a 2-channel, bridge tied load (BTL), switching audio power amplifier with integrated Σ-Δ modulator. The modulator accepts a single-ended, analog input signal and converts it to a switching waveform to drive speakers directly. One of the two modulators can control both...
