Maxim Integrated MAX11124ATI T

Description
The MAX11120-MAX11128 are 12-/10-/8-bit, high-speed, low-power, serial output successive-approximation register (SAR) analog-to-digital converters (ADCs) with external reference. They feature both internal and external clock modes, scan mode, and SampleSet™ technology (user-programmable analog input channel sequencer). The internal clock mode includes internal averaging for increased SNR, while the external clock mode allows for greater sequencing flexibility. The devices also have an integrated FIFO for high-speed data sampling and storage. They operate from a 2.35V to 3.6V supply and consume only 5.4mW at 1Msps.
