MAX11040GUU+集成電路（IC）的模數(shù)轉換器（ADC）規(guī)格書PDF中文資料

General Description

The MAX11040 is a 24-bit, 4-channel, simultaneous sampling, 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. Four modulators simultaneously convert each fully differential analog input with a programmable data output rate ranging from 0.25ksps to 64ksps. The device achieves 106dB SNR at 16ksps and 117dB SNR at 1ksps. The MAX11040 operates 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 device uses an internal crystal oscillator or an external source for clock.
