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-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).
