Maxim MAX11040KDBEVKIT#

Overview

The MAX11040K/MAX11060 are 24-/16-bit, 4-channel, simultaneous-sampling, sigma-delta analog-to-digital converters (ADCs). The devices allow 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 devices allows reading data from all the cascaded devices using a single command. Four modulators simultaneously convert each fully differential analog input with a programmable data output rate ranging from 0.25ksps to 64ksps. The devices achieve 106dB SNR at 16ksps and 117dB SNR at 1ksps (MAX11040K). The devices operate from a single +3V supply. The differential analog input range is ±2.2V when using the internal reference; an external reference is optional. Each input is overvoltage protected up to ±6V without damage. The devices use an internal crystal oscillator or an external source for clock.

The devices are available in a 38-pin TSSOP package specified over the -40°C to +105°C industrial temperature range.
