1. Introduce
-sl-a07 s provide high-performance, thermally efficient amplifier solutions. It delivers 2x20w into 8 loads or 1x40w into a 4 load.
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 +120c. Traditional thermal protection is also available in addition to robust overcurrent protection.
It operate from a single 8v to 22v 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.
