FEATURES  
DESCRIPTIO  
The 10-bit LTC®1850 and 12-bit LTC1851 are complete  
8-channel data acquisition systems. They include a flex-  
ible8-channelmultiplexer,a1.25Mspssuccessiveapproxi-  
mation analog-to-digital converter with sample-and-hold,  
an internal 2.5V reference and reference buffer amplifier,  
andaparalleloutputinterface. Themultiplexercanbecon-  
figured for single-ended or differential inputs, two gain  
ranges and unipolar or bipolar operation.

■
True Differential Inputs Reject Common Mode Noise  
The ADCs have a scan mode that will repeatedly cycle  
through all 8 multiplexer channels and can also be  
programmed with a sequence of up to 16 addresses and  
configurations that can be scanned in succession. The  
sequence memory can also be read back. 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 powered  
from a separate supply allowing for easy interface to 3V  
digital logic. Typical power consumption is 40mW at  
1.25Msps from a single 5V supply.
