    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-compatible 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 analog-to-digital conversion (ADC) offset.

    It includes internal references while the traditional reference pins and associated decoupling capacitors have been eliminated. The device is specified over the industrial temperature range (–40°C to 85°C).
