NCS2211DR2G from onsemi, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | Enable | input | Enable (LOW)/Shutdown (HIGH) control that must be actively driven and cannot be left floating; VIH is 90% of VCC minimum and VIL is 10% of VCC maximum. |
| 2 | Bias | passive | Bias output at (VCC−VEE)/2 that should be bypassed with a capacitor to reduce noise. |
| 3 | IN+ | input | Non-inverting (+) input; AC coupling the input is preferred to avoid a large DC output offset. |
| 4 | IN− | input | Inverting (−) input; the differential gain from input to speaker is AVD = 2 x R2/R1. |
| 5 | OUT+ | output | Positive differential output that can be driven to within 400 mV of either supply rail with an 8 Ω load. |
| 6 | VCC | power_in | Positive supply, specified for 2.7 V to 5.5 V and to be bypassed with 10 µF in parallel with 0.1 µF. |
| 7 | VEE | power_in | Negative supply, connected to GND for single-supply operation. |
| 8 | OUT− | output | Negative differential output that can be driven to within 400 mV of either supply rail with an 8 Ω load. |
