Product Description

SL-A07S provide high-performance, thermally efficient amplifier solutions. it delivers 2x20W into 8Ω loads or 1x40W into a 4Ω load.digital 20W stereo amplifier module.

An integrated limiting circuit prevents output clipping distortion, protects small speakers from transient voltages, and reduces power dissipation.

A thermal-foldback feature can be enabled to automatically reduce the output power at above a junction temperature of +120°C. Traditional thermal protection is also available in addition to robust overcurrent protection.

it operate from a single 8V to 28V supply and provide a high 67dB PSRR, eliminating the need for a regulated power supply. They offer up to 90% efficiency from a 12V supply.

Filterless modulation allows it to pass EN55022B EMI limits with 1m cables using only a low-cost ferrite bead and small-value capacitor on each output.

Both devices feature eight-digitally-controlled gain settings.

Comprehensive click-and-pop reduction circuitry minimizes noise coming into and out of shutdown.
