_______________General DescriptionThe MAX154/MAX158 and MX7824/MX7828 are high-speed, multi-channel analog-to-digital converters(ADCs). The MAX154 and

MX7824/MX7828fMAXpermits a maximum sampling rate of 50kHz perchannel when using the MAX158/MX7828 and 100kHzper channel when using the MAX154/MX7824.
