D2822M SOP8

Silicore · Audio Power OpAmps · SOP-8

D2822M SOP8 from Silicore, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 1OUT output Channel 1 audio power amplifier output. Drives speaker/headphone load (typ. 32 Ω / 16 Ω / 8 Ω); peak output current up to 0.8 A. AC-couple to load via output capacitor in single-ended mode.
2 Vcc power_in Positive supply voltage. Operating range 1.8 V to 7.5 V (absolute max 9.0 V). Typical 3-6 V; bypass with 10 µF electrolytic + 0.1 µF ceramic near the pin.
3 2OUT output Channel 2 audio power amplifier output. Drives speaker/headphone load; peak output current up to 0.8 A. In BTL bridge mode this pin is the anti-phase output relative to pin 1.
4 GND power_in Ground / 0 V reference for the amplifier and internal bias circuit.
5 2IN- input Channel 2 inverting input. Typically bypassed to ground through a 100 µF electrolytic (sets closed-loop gain of ~40 dB with internal feedback). Input impedance ≥ 100 kΩ.
6 2IN+ input Channel 2 non-inverting input. Audio signal input (AC-coupled through source impedance / 10 kΩ bias resistor). In BTL bridge mode this pin is tied to ground while pin 7 receives the signal.
7 1IN+ input Channel 1 non-inverting input. Audio signal input; source typically fed through a 10 kΩ bias/pull-down resistor to ground.
8 1IN- input Channel 1 inverting input. Typically bypassed to ground with a 100 µF electrolytic to set the AC gain. In BTL bridge mode this pin is fed from the output of the other channel to invert its signal.
