This topology SNR/SFDR Trade-off makes the ADS424x/422x well-suited for multi-carrier, • DC Offset Correction wide-bandwidth communications applications. • Output Interface Options: The ADS424x/422x have gain options that can be – 1.8V parallel CMOS interface used to improve SFDR performance at lower full-scale input ranges. These devices include a dc – Double data rate (DDR) LVDS with offset correction loop that can be used to cancel the programmable swing: ADC offset. Both DDR (double data rate) LVDS and – Standard swing: 350mV parallel CMOS digital output interfaces are available – Low swing: 200mV in a compact QFN-64 PowerPAD ™ package. • Supports Low Input Clock Amplitude The devices include internal references while the Down to 200mVPP traditional reference pins and associated decoupling • Package: QFN-64 (9mm × 9mm) capacitors have been eliminated. All devices are specified over the industrial temperature range ( –40°C to +85°C).
