COS8221BRZ from COSINE, 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 | VIN- | power_in | Negative input |
| 2 | RG | passive | Gain setting pin. For gains greater than 1, place a gain resistor between pin 2 & 3 |
| 3 | RG | passive | Gain setting pin. For gains greater than 1, place a gain resistor between pin 2 & 3 |
| 4 | VIN+ | power_in | Positive input |
| 5 | -VS | power_in | Negative supply |
| 6 | REF | input | Reference input. This Pin must be driven by low impedance or connected to ground |
| 7 | VOUT | output | Output |
| 8 | +VS | power_in | Positive supply |
