OPA1655DR

Texas Instruments · Operational Amplifier · SOIC-8

OPA1655DR 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 NC unconnected No internal connection.
2 -IN input Inverting input of the amplifier; input current should be limited to 10 mA and the input kept within (V-) - 0.5 V to (V+) + 0.5 V.
3 +IN input Noninverting input of the amplifier; input current should be limited to 10 mA and the input kept within (V-) - 0.5 V to (V+) + 0.5 V.
4 V- power_in Negative (lowest) power supply; supply range is 4.5 V to 36 V single or ±2.25 V to ±18 V dual.
5 NC unconnected No internal connection.
6 OUT output Amplifier output, rail-to-rail swing to within 250 mV of the supplies with a 2-kΩ load and up to 100 mA output current.
7 V+ power_in Positive (highest) power supply; supply range is 4.5 V to 36 V single or ±2.25 V to ±18 V dual.
8 NC unconnected No internal connection.
