OPA2727AIDR 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 | OUTA | output | Output of amplifier A; rail-to-rail class-AB output swings within 150mV of either rail at RL ≥ 100kΩ (AOL > 110dB), within 250mV at RL = 1kΩ, short-circuit current ±55mA, continuous output current 40mA. |
| 2 | -INA | input | Inverting input of amplifier A; differential input impedance 10¹¹ Ω ∥ 5 pF, input bias current ±500pA max, ESD-diode-clamped to supply rails (limit overload current to 10mA for inputs >300mV beyond supply). |
| 3 | +INA | input | Non-inverting input of amplifier A; common-mode range from V- to (V+)-2.5V, input bias current ±500pA max, CMRR 86dB min (94dB typ) over full CM range. |
| 4 | V- | power_in | Negative power supply; specified operating range 4V to 12V single-supply or ±2V to ±6V split-supply (abs max 13.2V total); bypass with 1nF ceramic in parallel with 1µF tantalum capacitor. |
| 5 | +INB | input | Non-inverting input of amplifier B; common-mode range from V- to (V+)-2.5V, input bias current ±500pA max, CMRR 86dB min (94dB typ) over full CM range. |
| 6 | -INB | input | Inverting input of amplifier B; differential input impedance 10¹¹ Ω ∥ 5 pF, input bias current ±500pA max, ESD-diode-clamped to supply rails (limit overload current to 10mA for inputs >300mV beyond supply). |
| 7 | OUTB | output | Output of amplifier B; rail-to-rail class-AB output swings within 150mV of either rail at RL ≥ 100kΩ (AOL > 110dB), within 250mV at RL = 1kΩ, short-circuit current ±55mA, continuous output current 40mA. |
| 8 | V+ | power_in | Positive power supply; specified operating range 4V to 12V single-supply or ±2V to ±6V split-supply (abs max 13.2V total); bypass with 1nF ceramic in parallel with 1µF tantalum capacitor. |
