I am considering both the LTC2512-24 wideband FIR filter SAR and LTC2380-24 narrowband SINC1 SAR for a design which is to have both good AC as well as DC specs. What is the passband ripple of the LTC2380-24?

The SINC1 filter response as shown in Figure 21 of the LTC2380-24 data sheet does not have a flat band area. The filter starts attenuating once the frequency is above DC. If you need a filter with a flat passband area the LTC2512-24 is the recommended way to go.
