TLE2142: Lower Iq 40V fast response amp solution

Part Number: TLE2142
Other Parts Discussed in Thread: LMP8672, OPA37

Hello team,

I'm looking for an alternative solution to TLE2142.
My client loves TLE2142 for 40V rail and 45V/us of fast response performance, but wants to reduce the power consumption in static condition if possible.
Is there any good option or development plan which has similar performance to TLE2142 with lower Iq?

Thanks in advance.

    Hello Sawamoto

    An alternative is the LMP8672 which offers better DC specifications and an impressive 45MHz. The slew rate, however, will be dictated by the current and since this is a lower current device it also has only 20V/us. 

    For a higher slew rate, an option is the OPA37. It's a decompensated op amp which means it has be to in a gain of 5 (minimum) but saves a lot of power compared to the TLE2142.
