DESCRIPTION
The ADS62PF49 is a dual-channel feedback reciever IC with sampling rates up to 250 MSPS. It allows a high-resolution, 14-bit output for a limited time followed by a low-resolution mode with a minimum of 8x longer time. It is pin-patible to the ADS62P49 and ADS62C17 dual ADCs.
The ADS62PF49 has gain options that can be used to improve SFDR performance at lower full-scale input ranges. It includes a dc offset correction loop that can be used to cancel the...
