AD92580C-DIGITAL AMPLIFIER POWER STAGE


AD92580C-2X20W Stereo (BTL) / 1X40W Mono (PBTL) / 4x10W (SE)
DIGITAL AMPLIFIER POWER STAGE DataSheet

Description
    AD92580C is a high performance stereo digital amplifier power stage. It can deliver 20Wx2CH output power (BTL) into 8Ω loudspeaker for stereo; or
40Wx1CH output power into 4Ω loudspeaker for mono in PBTL configuration within <1% THD+N at 24V supply. AD92580C also supports 10Wx4CH output
power into 4Ω loudspeaker for 4CH in SE configuration within <1% THD+N at 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. AD92580C’s chip is integrated
