Texas Instruments ADS422x / ADS424x Dual-Channel
Ultralow-Power ADCsTexas Instruments ADS422x and ADS424x Dual-Channel Analog-to-Digital Converters are low-speed variants of the ADS42xx ultra-low power family of ADCs. The 12-bit TI ADS422x and 14-bit TI ADS424x devices use innovative design techniques to achieve high-dynamic performance while consuming extremely low power with a 1.8V supply. This topology makes TI ADS422x and ADS424x Dual-Channel ADCs ideal for multi-carrier, wide-bandwidth communications applications.
