Single general-purpose op amp for industrial signal chains
The Texas Instruments TLV9351IDCKR is a single-channel general-purpose operational amplifier in a SC-70-5 package. It delivers a 3.5 MHz gain-bandwidth product and a 20 V/µs slew rate, with rail-to-rail output swing. The supply range spans 4.5 V to 40 V. Operating from -40°C to 125°C.
What the key ratings mean for your BOM
The 3.5 MHz GBW and 20 V/µs slew rate give this op amp enough bandwidth for sensor conditioning up to several hundred kHz — think shunt-resistor current sensing or thermocouple amplification — without the cost of a high-speed amplifier. The 60 mA output per channel can drive moderate loads like ADC inputs or a small relay coil directly, saving a buffer stage. Input bias current is 10 pA, so high-impedance sources (pH probes, photodiodes) won't see significant loading error.
Sourcing and lifecycle — active, no LTB risk
The TLV9351IDCKR carries an Active product status and is ROHS3 compliant. There is no last-time-buy notice or end-of-life signal on record. For dual-sourcing resilience, the TLV9362IDDFR is a close functional sibling — same general-purpose rail-to-rail family, 10.6 MHz GBW and 25 V/µs slew rate, but a dual-channel part in a different package (likely DFN). If your BOM calls for a single op amp in SC-70-5, the TLV9351IDCKR is the direct fit; the dual-channel variant requires a board respin.
