OPA2704UA 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, which swings to within 40mV of the rail with RL = 100kΩ and is rated for ±10mA output current with continuous short-circuit protection. |
| 2 | -In A | input | Inverting input of amplifier A, which is diode-clamped to the supply rails, so signals more than 0.3V beyond the rails must be limited to 10mA or less. |
| 3 | +In A | input | Non-inverting input of amplifier A, whose common-mode voltage range extends from (V-) - 0.3V to (V+) + 0.3V. |
| 4 | V- | power_in | Negative supply rail, specified for dual supplies of ±2V to ±6V and single-supply operation from the same rail. |
| 5 | +In B | input | Non-inverting input of amplifier B, whose common-mode voltage range extends from (V-) - 0.3V to (V+) + 0.3V. |
| 6 | -In B | input | Inverting input of amplifier B, which is diode-clamped to the supply rails, so signals more than 0.3V beyond the rails must be limited to 10mA or less. |
| 7 | Out B | output | Output of amplifier B, which swings to within 40mV of the rail with RL = 100kΩ and is rated for ±10mA output current with continuous short-circuit protection. |
| 8 | V+ | power_in | Positive supply rail, specified for single supply 4V to 12V with an absolute maximum V+ to V- of 13.2V. |
