LTC2450  
Easy-to-Use, Ultra-Tiny  
16-Bit DS ADC  
Features  
Description  
The LTC®2450 is an ultra-tiny 16-bit analog-to-digital  
converter. The LTC2450 uses a single 2.7V to 5.5V supply,  
accepts a single-ended analog input voltage, and commu-  
nicates through an SPI interface. It includes an integrated  
oscillator that does not require any external components.  
It uses a delta-sigma modulator as a converter core and  
providessingle-cyclesettlingtimeformultiplexedapplica-  
tions. The converter is available in a 6-pin, 2mm × 2mm  
DFN package. The internal oscillator does not require any  
external components. The LTC2450 includes a proprietary  
input sampling scheme that reduces the average input  
sampling current several orders of magnitude.

The LTC2450 is capable of up to 30 conversions per sec-  
ond and, due to the very large oversampling ratio, has  
extremelyrelaxedantialiasingrequirements.TheLTC2450  
includes continuous internal offset and full-scale calibra-  
tionalgorithmswhicharetransparenttotheuser,ensuring  
accuracy over time and over the operating temperature  
range. The converter uses its power supply voltage as the  
reference voltage and the single-ended, rail-to-rail input

Instrumentation  
Following a conversion, the LTC2450 can automatically  
enter a sleep mode and reduce its power to less than  
200nA. If the user samples the ADC once a second, the  
LTC2450 consumes an average of less than 50µW from  
a 2.7V supply.
