LTC1852/LTC1853  
8-Channel, 10-Bit/12-Bit,  
400ksps, Low Power, Sampling ADCs  
FEATURES  
DESCRIPTION  
The 10-bit LTC®1852 and 12-bit LTC1853 are complete  
8-channeldataacquisitionsystems.Theyincludeaflexible  
8-channel multiplexer, a 400ksps successive approxima-  
tionanalog-to-digitalconverter,aninternalreferenceanda  
paralleloutputinterface.Themultiplexercanbeconfigured  
forsingle-endedordifferentialinputs,twogainrangesand  
unipolar or bipolar operation. The ADCs have a scan mode  
thatwillrepeatedlycyclethroughall8multiplexerchannels  
and can also be programmed to sequence through up to  
16 addresses and configurations. The sequence can also  
be read back from internal memory.

Pin Compatible up-grade 1.25Msps 10-Bit LTC1850  
and 12-Bit LTC1851  
The reference and buffer amplifier provide pin strappable  
ranges of 4.096V, 2.5V and 2.048V. The parallel output  
includes the 10-bit or 12-bit conversion result plus the  
4-bit multiplexer address. The digital outputs are pow-  
ered from a separate supply allowing for easy interface  
to 3V digital logic. Typical power consumption is 10mW  
at 400ksps from a single 5V supply and 3mW at 250ksps  
from a single 3V supply.
