The ADS424x and ADS422x family of devices are low-speed variants of the ADS42xx
ultralow-power family of dual-channel, 14-bit/12-bit analog-to-digital converters (ADCs).
Innovative design techniques are used to achieve high-dynamic performance, while consuming
extremely low power with 1.8-V supply. This topology makes the ADS424x/422x well-suited for
multi-carrier, wide-bandwidth communications applications.
The ADS424x/422x have gain options that can be used to improve SFDR performance at lower full-scale input
ranges. These devices include a dc offset correction loop that can be used to cancel the ADC offset. Both DDR
(double data rate) LVDS and parallel CMOS digital output interfaces are available in a compact VQFN-64
The devices include internal references while the traditional reference pins and associated decoupling capacitors
have been eliminated. All devices are specified over the industrial temperature range (–40°C to 85°C).
