LTC1857/LTC1858/LTC1859

Converters with Shutdown  
FEATURES  
DESCRIPTION  
The LTC®1857/LTC1858/LTC1859 are 8-channel, low  
power,12-/14-/16-bit,100ksps,analog-to-digitalconvert-  
ers (ADCs). These SoftSpan™ ADCs can be software-  
programmed for 0V to 5V, 0V to 10V, ±5V or ±10V inpꢀt  
spans and operate from a single 5V sꢀpply. The 8-channel  
mꢀltiplexer can be programmed for single-ended inpꢀts  
or pairs of differential inpꢀts or combinations of both. In  
addition, all channels are faꢀlt protected to ±25V. A faꢀlt  
condition on any channel will not affect the conversion  
resꢀlt of the selected channel.
