Audio Switching Amplifier

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 output stages providing twice the current and almost twice the efficiency for single-channel applications. Both modulators can also control external power devices for arbitrarily high output power. A digital, microprocessor-compatible interface provides control of reset, mute, and PGA gain, as well as feedback signals for thermal and overcurrent error conditions. The output stage can operate over a power supply voltages range of 8 V to 20 V. The analog modulator and digital logic operate from a 5 V supply.
