MSKSEMI · Operational Amplifier · SOP-8
OPA2333AIDR-MS from MSKSEMI, in a SOP-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 | OUTA | output | Output of channel A; the datasheet specifies rail-to-rail output that swings within 50 mV of the rails. |
| 2 | -INA | input | Inverting input of channel A, with a common-mode range that extends 100 mV beyond the rails. |
| 3 | +INA | input | Noninverting input of channel A, with a common-mode range that extends 100 mV beyond the rails. |
| 4 | V- | power_in | Negative (lowest) power supply; single or dual supplies from 1.8 V (±0.9 V) to 5.5 V (±2.75 V) can be used. |
| 5 | +INB | input | Noninverting input of channel B, with a common-mode range that extends 100 mV beyond the rails. |
| 6 | -INB | input | Inverting input of channel B, with a common-mode range that extends 100 mV beyond the rails. |
| 7 | OUTB | output | Output of channel B; the datasheet specifies rail-to-rail output that swings within 50 mV of the rails. |
| 8 | V+ | power_in | Positive (highest) power supply; single or dual supplies from 1.8 V (±0.9 V) to 5.5 V (±2.75 V) can be used. |
