OPA2990IDDFR from Texas Instruments, in a SOT-23-8. 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 | OUT1 | output | Channel 1 output capable of sourcing or sinking ±80mA short-circuit current with rail-to-rail swing. |
| 2 | IN1- | input | Channel 1 inverting input with common-mode input range (V-)-0.2V to (V+)+0.2V and ±10pA input bias current. |
| 3 | IN1+ | input | Channel 1 non-inverting input with common-mode input range (V-)-0.2V to (V+)+0.2V and ±10pA input bias current. |
| 4 | V- | power_in | Negative (lowest) power supply; must maintain 2.7V to 40V total supply span between V- and V+. |
| 5 | IN2+ | input | Channel 2 non-inverting input with common-mode input range (V-)-0.2V to (V+)+0.2V and ±10pA input bias current. |
| 6 | IN2- | input | Channel 2 inverting input with common-mode input range (V-)-0.2V to (V+)+0.2V and ±10pA input bias current. |
| 7 | OUT2 | output | Channel 2 output capable of sourcing or sinking ±80mA short-circuit current with rail-to-rail swing. |
| 8 | V+ | power_in | Positive (highest) power supply; supports 2.7V to 40V total supply operation (±1.35V to ±20V dual supply). |
