Description

General part information

ADS4245-EP Series

The ADS4245 is a low-speed variant of the ADS42xx ultralow-power family of dual-channel, 14-bit analog-to-digital converters (ADCs). Innovative design techniques are used to achieve high-dynamic performance, while consuming extremely low power with 1.8V supply. This topology makes the ADS4245 well-suited for multi-carrier, wide-bandwidth communications applications.

The ADS4245 has gain options that can be used to improve SFDR performance at lower full-scale input ranges. These device includes 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 PowerPAD™ package.

The device includes internal references while the traditional reference pins and associated decoupling capacitors have been eliminated. The ADS4245 is specified over the military temperature range (–55°C to 125°C).
