ADS4245-EP Ultralow-Power ADC

The ADS4245 is a low-speed variant of the ADS42xx ultralow-power family of dual-channel, 14-bit analogto-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 applic.
