Integrator note — TLV3541IDBVR
Single general-purpose op-amp in a SOT-23-5 package, 200 MHz -3 dB bandwidth, 150 V/µs slew rate.
Slew rate — the real speed limiter in the feedback loop
At 150 V/µs, the TLV3541IDBVR is faster than the TLV9351IDCKR (20 V/µs) and the TLV9362IDDFR (25 V/µs). That delta matters when preserving signal integrity above 1 MHz at full output swing.
ROHS3 compliant. No official replacement from TI, but the TLV9351IDCKR is a functional alternative if you can trade speed for lower offset and supply current.
