Dual-Channel, 12-Bit, 250-MSPS Analog-to-Digital Converter (ADC) - ADS4229

ADS4229 (ACTIVE)

Dual-Channel, 12-Bit, 250-MSPS Analog-to-Digital Converter (ADC)

 

Description

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).
