OPA2356AIDR from Texas Instruments, 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 | OUT A | output | Output of amplifier A; rail-to-rail output stage swings within 100mV of the supply rails and can drive a back-terminated 75Ω cable. |
| 2 | -IN A | input | Inverting input of amplifier A, internally ESD-protected with diodes to the supply rails and current-limited to 10mA if driven beyond the rails. |
| 3 | +IN A | input | Non-inverting input of amplifier A; common-mode input voltage range extends 100mV below V- up to 1.5V below V+. |
| 4 | V- | power_in | Negative supply pin; device operates from a specified 2.7V to 5.5V single/dual supply range (2.5V to 5.5V operating range) with 7.5V absolute maximum V+ to V-. |
| 5 | +IN B | input | Non-inverting input of amplifier B; common-mode input voltage range extends 100mV below V- up to 1.5V below V+. |
| 6 | -IN B | input | Inverting input of amplifier B, internally ESD-protected with diodes to the supply rails and current-limited to 10mA if driven beyond the rails. |
| 7 | OUT B | output | Output of amplifier B; rail-to-rail output stage swings within 100mV of the supply rails and can drive a back-terminated 75Ω cable. |
| 8 | V+ | power_in | Positive supply pin; specified voltage range +2.7V to +5.5V (operating range 2.5V to 5.5V), requires a bypass capacitor for stable high-frequency operation. |
