Lead (QFN) Package
The ADS4249 is a member of the ADS42xx ultralow-power family of dual-channel, 12-bit and 14-bit analog-to-digital converters (ADCs). Innovative design techniques are used to achieve high dynamic performance, while consuming extremely low power with a 1.8-V supply. This topology makes the ADS4249 well-suited for multi-carrier, wide-bandwidth communications applications.
The ADS4249 has gain options that can be used to improve SFDR performance at lower full-scale input ranges. This device also includes a dc offset correction loop that can be used to cancel the ADC offset. Both DDR LVDS and parallel CMOS digital output interfaces are available in a compact QFN-64 PowerPAD package.
The device includes internal references while the traditional reference pins and associated decoupling capacitors have been eliminated. The ADS4249 is specified over the industrial temperature range (–40°C to 85°C).
