OPA2703EA from Texas Instruments, in a VSSOP-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, which swings to within 40 mV of the rail with RL = 100 kΩ and supplies output current of ±10 mA when |
| 2 | -In A | input | Inverting input of amplifier A; the input common-mode range extends 300 mV beyond each supply rail, and input signals swinging more than 0.3 V beyond the rails should be current-limited to 10 mA or less. |
| 3 | +In A | input | Non-inverting input of amplifier A; the input common-mode range extends 300 mV beyond each supply rail, and input signals swinging more than 0.3 V beyond the rails should be current-limited to 10 mA or less. |
| 4 | V- | power_in | Negative power supply; the device is specified for dual supplies of ±2 V to ±6 V or single supply of 4 V to 12 V, with a absolute maximum supply voltage (V+ to V-) of 13.2 V. |
| 5 | +In B | input | Non-inverting input of amplifier B; the input common-mode range extends 300 mV beyond each supply rail, and input signals swinging more than 0.3 V beyond the rails should be current-limited to 10 mA or less. |
| 6 | -In B | input | Inverting input of amplifier B; the input common-mode range extends 300 mV beyond each supply rail, and input signals swinging more than 0.3 V beyond the rails should be current-limited to 10 mA or less. |
| 7 | Out B | output | Output of amplifier B, which swings to within 40 mV of the rail with RL = 100 kΩ and supplies output current of ±10 mA when |
| 8 | V+ | power_in | Positive power supply; the device is specified for dual supplies of ±2 V to ±6 V or single supply of 4 V to 12 V, with an absolute maximum supply voltage (V+ to V-) of 13.2 V. |
