Hi Sean,

I recommend taking a look at the TLV9304 or OPA4990. The TLV9304 is a very close in performance to the MC33174. The OPA4990 is higher performance and Rail to Rail input compared to the MC33174.

If higher bandwidth is needed please take a look at the TLV9352 and OPA2991 (qual channel will be TLV9354/OPA4991 when it is available).

Thank you,

Tim Claycomb

Hi Sean,

Both the TLV9304 and OPA4990 appear to have the same pin out at the MC33174DT.

Thank you,
