LTC2453

Differential, 16-Bit ΔΣ ADC

With I C Interface  
DESCRIPTION  
FEATURES  
The LTC®2453 is an ultra-tiny, fully differential, 16-bit,  
analog-to-digital converter. The LTC2453 uses a single  
2.7V to 5.5V supply and communicates through an I2C  
interface. The ADC is available in an 8-pin, 3mm × 2mm  
DFNpackage.Itincludesanintegratedoscillatorthatdoes  
notrequireanyexternalcomponents.Itusesadelta-sigma  
modulator as a converter core and has no latency for  
multiplexed applications. The LTC2453 includes a pro-  
prietary input sampling scheme that reduces the average  
inputsamplingcurrentseveralordersofmagnitudelower  
than conventional delta-sigma converters. Additionally,  
due to its architecture, there is negligible current leakage  
between the input pins.

The LTC2453 can sample at 60 conversions per second,  
and due to the very large oversampling ratio, has ex-  
tremely relaxed antialiasing requirements. The LTC2453  
includescontinuousinternaloffsetandfull-scalecalibration  
algorithms which are transparent to the user, ensuring  
accuracy over time and over the operating temperature

Data Acquisition  
Following a single conversion, the LTC2453 can auto-  
matically enter a sleep mode and reduce its power to less  
than 0.2μA. If the user reads the ADC once a second, the  
LTC2453 consumes an average of less than 50μW from  
a 2.7V supply.
