OPA2353UA from Texas Instruments, in a SO-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 | V+ | power_in | Positive supply voltage, operating range 2.7V to 5.5V, all circuits referenced to this rail. |
| 2 | Out B | output | Output of operational amplifier B, voltage swing to within 10mV of supply rails with 10kΩ load, output current ±40mA. |
| 3 | -In B | input | Inverting input of operational amplifier B, common-mode input voltage range (V-)-0.1V to (V+)+0.1V. |
| 4 | +In B | input | Non-inverting input of operational amplifier B, common-mode input voltage range (V-)-0.1V to (V+)+0.1V. |
| 5 | V- | power_in | Negative supply voltage (ground reference), 0V for single-supply operation. |
| 6 | +In A | input | Non-inverting input of operational amplifier A, common-mode input voltage range (V-)-0.1V to (V+)+0.1V. |
| 7 | -In A | input | Inverting input of operational amplifier A, common-mode input voltage range (V-)-0.1V to (V+)+0.1V. |
| 8 | Out A | output | Output of operational amplifier A, voltage swing to within 10mV of supply rails with 10kΩ load, output current ±40mA. |
