FEATURES  
DESCRIPTION  
The LTC®2450-1 is a low power, ultra-tiny 16-bit analog-  
to-digital converter designed for space constrained ap-  
plications requiring 16-bit performance. The LTC2450-1  
uses a single 2.7V to 5.5V supply, accepts a single-ended  
analog input voltage, and communicates through an SPI  
interface. It includes an integrated oscillator that does  
not require any external components. The delta-sigma  
modulator converter core provides single-cycle settling  
time for multiplexed applications. The converter is avail-  
able in a 6-pin, 2mm × 2mm DFN package. The LTC2450-1  
implements a proprietary input sampling scheme that

The LTC2450-1 is capable of up to 60 conversions per  
second and, due to the very large oversampling ratio, has

Following a conversion, the LTC2450-1 can automatically  
enter a sleep mode and reduce its power to less than  
500nA. At an output rate of 1Hz, the LTC2450-1 consumes  
an average of less than 25μW from a 2.7V supply.
