OPA4684IDR

Texas Instruments · Operational Amplifier · SOIC-14

OPA4684IDR from Texas Instruments, in a SOIC-14. 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 Output A output Channel A amplifier output, with 120mA output current capability.
2 -Input A input Channel A inverting input, the low-impedance current-feedback input (about 4.0Ω open-loop) that connects to the feedback resistor.
3 +Input A input Channel A noninverting input with 50kΩ
4 +V power_in Positive supply, +5V to +12V single-supply or +2.5V to +6.0V dual-supply operation, with a 0.1µF decoupling capacitor placed within 0.25".
5 +Input B input Channel B noninverting input with 50kΩ
6 -Input B input Channel B inverting input, the low-impedance current-feedback input that connects to the feedback resistor.
7 Output B output Channel B amplifier output, with 120mA output current capability.
8 Output C output Channel C amplifier output, with 120mA output current capability.
9 -Input C input Channel C inverting input, the low-impedance current-feedback input that connects to the feedback resistor.
10 +Input C input Channel C noninverting input with 50kΩ
11 -V power_in Negative supply (ground in single-supply operation); total supply across the pins must not exceed ±6.5V absolute maximum.
12 +Input D input Channel D noninverting input with 50kΩ
13 -Input D input Channel D inverting input, the low-impedance current-feedback input that connects to the feedback resistor.
14 Output D output Channel D amplifier output, with 120mA output current capability.
