OPA4137U

Texas Instruments · FET Input Amplifiers · SOIC-14

OPA4137U 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 Out A output Output of amplifier A, which can swing to (V-)+1.2V and (V+)-1.1V with a 10kΩ load at VS = ±15V.
2 -In A input Inverting input of amplifier A; input current should be limited to 2mA when the input exceeds the supply rails.
3 +In A input Non-inverting input of amplifier A; common-mode range runs from (V-)+3V to (V+).
4 V+ power_in Positive supply, 4.5V to 36V single-supply (±2.25V to ±18V dual), bypassed with a 10nF or larger ceramic capacitor.
5 +In B input Non-inverting input of amplifier B; common-mode range runs from (V-)+3V to (V+).
6 -In B input Inverting input of amplifier B; input current should be limited to 2mA when the input exceeds the supply rails.
7 Out B output Output of amplifier B, which can swing to (V-)+1.2V and (V+)-1.1V with a 10kΩ load at VS = ±15V.
8 Out C output Output of amplifier C, which can swing to (V-)+1.2V and (V+)-1.1V with a 10kΩ load at VS = ±15V.
9 -In C input Inverting input of amplifier C; input current should be limited to 2mA when the input exceeds the supply rails.
10 +In C input Non-inverting input of amplifier C; common-mode range runs from (V-)+3V to (V+).
11 V- power_in Negative supply or ground in single-supply use; total supply (V+ to V-) is 4.5V to 36V (±2.25V to ±18V).
12 +In D input Non-inverting input of amplifier D; common-mode range runs from (V-)+3V to (V+).
13 -In D input Inverting input of amplifier D; input current should be limited to 2mA when the input exceeds the supply rails.
14 Out D output Output of amplifier D, which can swing to (V-)+1.2V and (V+)-1.1V with a 10kΩ load at VS = ±15V.
