Precision dual op-amp for signal-conditioning loops
The OP297GSZ-REEL: The 80 µV typical input offset and 50 pA input bias current let it resolve microvolt-level signals from high-impedance sources without the output error budget being consumed by the amplifier's own DC errors.
Supply rails and temperature envelope
Runs from a single 4 V supply up to 40 V total, or split rails ±2 V to ±20 V — the wide span covers 5 V and ±15 V industrial rails without a secondary regulator. Each channel draws 525 µA quiescent, so the dual package adds about 1.05 mA to the board's analog rail budget — negligible in a mixed-signal system but worth tracking in a battery-powered loop-powered transmitter.
Sourcing and compliance posture
RoHS3 compliant (2011/65/EU + 2015/863), the part ships without the six original restricted substances plus the four phthalates — no exemption declarations needed for EU-market equipment.
Board-fit and footprint considerations
Surface-mount assembly on Tape & Reel (7-inch reel, standard 8-mm tape width) feeds into any pick-and-place line; the reel quantity is confirmed at order.
