OPA2171AQDGKRQ1

Texas Instruments · Operational Amplifier · MSOP-8

OPA2171AQDGKRQ1 from Texas Instruments, in a MSOP-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 Channel A output with voltage swing from (V-) + 0.35 V to (V+) - 0.35 V, source current 25 mA and sink current 37 mA.
2 -IN A input Channel A inverting input operates within common mode voltage range (V-) - 0.1 to (V+) - 2 V with maximum input current ±10 mA.
3 +IN A input Channel A non-inverting input operates within common mode voltage range (V-) - 0.1 to (V+) - 2 V with maximum input current ±10 mA.
4 V- power_in Negative (lowest) power supply with nominal operating range 4.5 to 36 V between V+ and V- at operating temperature -40°C to 125°C.
5 +IN B input Channel B non-inverting input operates within common mode voltage range (V-) - 0.1 to (V+) - 2 V with maximum input current ±10 mA.
6 -IN B input Channel B inverting input operates within common mode voltage range (V-) - 0.1 to (V+) - 2 V with maximum input current ±10 mA.
7 OUT B output Channel B output with voltage swing from (V-) + 0.35 V to (V+) - 0.35 V, source current 25 mA and sink current 37 mA.
8 V+ power_in Positive (highest) power supply with nominal operating range 4.5 to 36 V between V+ and V- at operating temperature -40°C to 125°C.
