The ADS4229 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 ADS4229 well-suited for multi-carrier, wide-bandwidth communications applications.
The ADS4229 has gain options that can be used to improve spurious-free dynamic range
(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 double data rate (DDR) low-voltage
differential signaling (LVDS) and parallel complementary metal oxide semiconductor (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 ADS4229 is specified over the industrial
temperature range (40°C to +85°C).
