Product details

Supply range and quiescent current — sizing the rail budget

Spanning 2.7 V to 36 V, this op-amp fits designs from battery-operated 3.3 V sensor interfaces to ±18 V industrial control loops. The 475 µA supply current per channel (950 µA total for both) keeps the power budget lean for multi-channel boards. Input bias current is 8 pA, which minimizes offset errors in high-impedance sensor circuits.

Output drive and temperature range

The rail-to-rail output stage maintains swing close to the supply rails, preserving dynamic range in low-voltage systems.

Frequently asked questions

What is the difference between OPA2171AID and OPA2171AIDBQ?

The OPA2171AID ships in a tube (8-SOIC), while the OPA2171AIDBQ is the same die in a tape-and-reel package variant. Electrical specifications are identical.

What are the alternatives or equivalents to OPA2171AID?

The OPA2171AID is a dual general-purpose op-amp. Pin-compatible alternatives within the same family include the OPA2171AIDBQ (tape-and-reel) and the single-channel OPA171 series. For a different supply range or speed, consider the OPA2188 (zero-drift) or OPA2192 (36 V, 10 MHz).
