ADS4242 Ultralow-Power ADC

The ADS424x and ADS422x family of devices are low-speed variants of the ADS42xx ultralow-power family of dual-channel, 14-bit/12-bit analog-to-digital converters (ADCs). Innovative design techniques are used to achieve high-dynamic performance, while consuming extremely low power with 1.8-V supply. This topology makes the ADS424x/422x well-suited for multi-c.
