The OPA703UA: Gain-bandwidth product is 1 MHz and slew rate is 0.6 V/µs. Supply current is 160 µA per channel. Input bias current is 1 pA.
Supply voltage range is 4 V to 12 V.
The standard SOIC-8 footprint applies — no thermal pad, no exposed paddle. The shipping medium is Tube, so factor that into your pick-and-place feeder setup if you're ordering in volume.
Yes, the OPA703UA has a rail-to-rail output stage. The input common-mode range is not rail-to-rail — it extends from the negative rail to about 1.5 V below the positive rail — so the output swing is the key advantage for single-supply designs.
No direct pin-compatible replacement is listed by the manufacturer. For a higher-speed alternative with similar supply range, consider the TLV9351IDCKR (3.5 MHz GBW, 20 V/µs slew rate, 600 µA supply, rail-to-rail I/O, -40°C to 125°C) — but verify the pinout and compensation before substituting. The OPA703UA remains active, so a replacement is not urgent.
