It can deliver 10W x 2CH output power into 8Ω loudspeaker for stereo or 20W x 1ch output power into 4Ω loudspeaker for mono in BTL configuration within <1% THD+N at 15V ~ 24V supply. A patented, built-in anti-pop function can reduce the speaker’s pop noise without requiring complex anti-pop sequence in PWM input. The AD92580’s chip is integrated with over-temperature, over-current, and under-voltage protection circuits. These additions safeguard the AD92580 against fault conditions that could damage the chip and system catastrophically. Functional Block Di...
