COSINA333MRA from COSINE, in a MSOP-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 | RG | passive | Gain setting pin; for gains greater than 1, place a gain resistor between pins 1 and 8. |
| 2 | VIN- | power_in | Negative input. |
| 3 | VIN+ | power_in | Positive input. |
| 4 | -VS | power_in | Negative supply. |
| 5 | REF | input | Reference input; must be driven by low impedance or connected to ground. |
| 6 | VOUT | output | Output. |
| 7 | +VS | power_in | Positive supply. |
| 8 | RG | passive | Gain setting pin; for gains greater than 1, place a gain resistor between pins 1 and 8. |
