LTC2452  
Ultra-Tiny, Differential, 16-Bit  
ΔΣ ADC with SPI Interface  
FEATURES  
DESCRIPTION  
The LTC®2452 is an ultra-tiny, fully differential, 16-bit,  
analog-to-digital converter. The LTC2452 uses a single  
2.7V to 5.5V supply and communicates through an SPI

interface. The ADC is available in an 8-pin, 3mm × 2mm  
DFNpackageorTSOT-23package.Itincludesanintegrated  
oscillator that does not require any external components.  
It uses a delta-sigma modulator as a converter core and  
has no latency for multiplexed applications. The LTC2452  
includesaproprietaryinputsamplingschemethatreduces  
the average input sampling current several orders of  
magnitude when compared to conventional delta-sigma  
converters. Additionally, due to its architecture, there is  
negligible current leakage between the input pins.

Industrial Process Control  
Following a single conversion, the LTC2452 can automati-  
cally enter a sleep mode and reduce its supply current to  
less than 0.2µA. If the user reads the ADC once a second,  
the LTC2452 consumes an average of less than 50µW  
from a 2.7V supply.
