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
One of the two modulators can control both output stages providing twice the current and almost twice the efficiency for single-channel applications. 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. APPLICATIONS
