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.

The LTC1400 converts 0V to 4.096V unipolar inputs from  
a single 5V supply and ±2.048V bipolar inputs from ±5V  
supplies. Maximum DC specs include ±1LSB INL, ±1LSB  
DNLand45ppm/°Cdriftovertemperature.GuaranteedAC  
performance includes 70dB S/(N + D) and –76dB THD at  
an input frequency of 100kHz, over temperature.
