Maxim Integrated MAX11040

The MAX11040 is a 24-bit, 4-channel, simultaneoussampling, sigma-delta analog-to-digital converter (ADC). The device allows simultaneous sampling of as many as 32 channels using a built-in cascade feature to synchronize as many as eight devices. The serial interface of the MAX11040 allows reading data from all the cascaded devices using a single command.
