The 1.7 V minimum supply span lets the OPA387DBVT run directly from a single-cell Li-ion battery down to its end-of-discharge voltage.
The 30 pA input bias current is low enough that a 10 kΩ source resistor contributes only 0.3 µV of additional offset — negligible in most designs, but worth checking if the source impedance climbs above 100 kΩ.
The maximum input offset voltage is specified at 250 µV. The datasheet typical value is lower, but the 250 µV max is the number to use for worst-case accuracy budgeting.
The TI TLV9351IDCKR is a functional alternative in the same SOT-23-5 footprint. It offers a 3.5 MHz GBW and 20 V/µs slew rate versus the OPA387DBVT's 5.7 MHz and 2.8 V/µs, so the choice depends on whether bandwidth or slew rate is the limiting factor in your signal path.
