Precision op-amp for low-drift signal chains
The OP97FSZ-REEL7 is a single-channel general-purpose operational amplifier from Analog Devices, built for precision signal conditioning where input offset and bias current matter more than raw bandwidth. With a maximum input offset voltage of 30 µV and an input bias current of just 30 pA, this part suits thermocouple amplifiers, strain-gauge front-ends, and other DC-accurate analog paths where the error budget is tight.
900 kHz bandwidth at 380 µA supply draw
The -3 dB bandwidth of 900 kHz paired with a 0.2 V/µs slew rate defines the small-signal response ceiling — the part tracks slow-changing sensor outputs without phase lag, but the slew rate limits full-swing step response to roughly 10 µs per volt of output swing. Quiescent current is 380 µA, which keeps the self-heating low in the 8-SOIC package and makes the part viable for multi-channel boards where each op-amp's supply draw adds up across the rail. Supply span ranges from 4 V minimum to 40 V maximum, so the same BOM line serves both 5 V single-supply sensor interfaces and ±15 V industrial analog front-ends without a voltage-grade change.
