FEATURES  
DESCRIPTIO  
TheLTC®1860/LTC1861are12-bitA/Dconvertersthatare  
offered in MSOP and SO-8 packages and operate on a  
single 5V supply. At 250ksps, the supply current is only  
850µA. The supply current drops at lower speeds because  
the LTC1860/LTC1861 automatically power down to a  
typical supply current of 1nA between conversions. These  
12-bitswitchedcapacitorsuccessiveapproximationADCs  
include sample-and-holds.TheLTC1860hasadifferential  
analoginputwithanadjustablereferencepin.TheLTC1861  
offers a software-selectable 2-channel MUX and an ad-  
justable reference pin on the MSOP version.  
12-Bit 250ksps ADCs in MSOP Package  
Single 5V Supply  
Low Supply Current: 850µA (Typ)  
Auto Shutdown Reduces Supply Current  
to 2µA at 1ksps  
True Differential Inputs  
1-Channel (LTC1860) or 2-Channel (LTC1861)  
Versions  
SPI/MICROWIRETM Compatible Serial I/O  
High Speed Upgrade to LTC1286/LTC1298  
Pin Compatible with 16-Bit LTC1864/LTC1865  
The 3-wire, serial I/O, MSOP or SO-8 package and  
extremely high sample rate-to-power ratio make these  
ADCs ideal choices for compact, low power, high speed  
systems.

TheseADCscanbeusedinratiometricapplicationsorwith  
external references. The high impedance analog inputs  
and the ability to operate with reduced spans down to 1V  
full scale, allow direct connection to signal sources in  
many applications, eliminating the need for external gain  
stages.
