AD52068 Integrated Circuit by ESMT | E-TSSOP-28L Package

AD52068 | Stereo Class-D Audio Amplifier IC
Package: E-TSSOP-28L | Pins: 28 | Supply Voltage: 4.5V – 26V (up to 30V abs. max)

The AD52068 from ESMT is a high-efficiency stereo Class-D audio amplifier IC with an adjustable power limit function designed to protect loudspeakers while delivering robust performance. Operating from a single supply (4.5V–26V) with a built-in 5V LDO regulator, this device achieves up to 88% efficiency, enabling filter-free, heatsink-less operation in most applications.

It supports both BTL (20W/channel into 8Ω @ 24V, <1% THD+N) and PBTL mono (40W into 4Ω @ 24V) configurations, making it suitable for TVs, consumer audio, portable speakers, and monitor systems.
