FEATURES  
DESCRIPTION  
The LTC®1864/LTC1865 are 16-bit A/D converters that  
are 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  
becausetheLTC1864/LTC1865automaticallypowerdown  
between conversions. These 16-bit switched capacitor  
successive approximation ADCs include sample-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.

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