400ksps ADC with  
Shutdown

DESCRIPTIO  
FEATURES  
TheLTC®1400isacomplete400ksps,12-bitA/Dconverter  
which draws only 75mW from 5V or ±5V supplies. This  
easy-to-use device comes complete with a 200ns sample-  
and-hold and a precision reference. Unipolar and bipolar  
conversion modes add to the flexibility of the ADC. The  
LTC1400 has two power saving modes: Nap and Sleep.  
In Nap mode, it consumes only 6mW of power and can  
wake up and convert immediately. In the Sleep mode, it  
consumes 30μW of power typically. Upon power-up from  
Sleepmode,areferenceready(REFRDY)signalisavailable  
in the serial data word to indicate that the reference has  
settled and the chip is ready to convert.
