1- and 2-Channel ADCs in MSOP  
FEATURES  
DESCRIPTION  
The LTC®1860/LTC1861 are 12-bit A/D converters that are  
offeredinMSOPandSO-8packagesandoperateonasingle  
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-bit  
switchedcapacitorsuccessiveapproximationADCsinclude  
sample-and-holds. The LTC1860 has a differential analog  
input with an adjustable reference pin. The LTC1861 offers  
a software-selectable 2-channel MUX and an adjustable  
reference pin on the MSOP version.

Guaranteed Operation to 125°C (MSOP Package)  
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.  
APPLICATIONS

High Speed Data Acquisition  
Portable or Compact Instrumentation  
Low Power Battery-Operated Instrumentation

n
These ADCs can be used in ratiometric applications or  
with external references. The high impedance analog in-  
puts 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.
