FEATURES  
DESCRIPTIO  
TheLTC®1864/LTC1865are16-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 LTC1864/LTC1865 automatically power down  
between conversions. These 16-bit switched capacitor  
successiveapproximationADCsincludesample-and-holds.  
The LTC1864 has a differential analog input with an  
adjustable reference pin. The LTC1865 offers a software-  
selectable 2-channel MUX and an adjustable reference pin  
on the MSOP version.  
16-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 (LTC1864) or 2-Channel (LTC1865)  
Versions  
SPI/MICROWIRETM Compatible Serial I/O  
16-Bit Upgrade to 12-Bit LTC1286/LTC1298  
Pin Compatible with 12-Bit LTC1860/LTC1861  
The 3-wire, serial I/O, small 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.  
U
APPLICATIO S  
High Speed Data Acquisition  
Portable or Compact Instrumentation  
These ADCs can be used in ratiometric applications or  
with 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.  
Low Power Battery-Operated Instrumentation
