For dual-sourcing resilience, the TLV9362IDDFR is a close functional peer — same dual-channel count, 10.6 MHz GBW, 25 V/µs slew, and 2.7-40 V supply — but verify pin-compatibility against your layout before substituting.
A close functional equivalent is the TLV9362IDDFR, also a dual-channel general-purpose op-amp with rail-to-rail output, 10.6 MHz GBW, 25 V/µs slew, and 2.7-40 V supply. Verify pin-compatibility before substituting.
The OPA2991 offers a 4.5 MHz gain-bandwidth product and 21 V/µs slew rate, while the OPA2990 is a lower-speed variant typically specified at 1 MHz GBW and 0.5 V/µs slew. The OPA2991 is the higher-bandwidth choice for faster signal chains.
