converters with an integrated precision reference and  
a selectable 250sps or 1ksps output rate. They use a  
single 2.7V to 5.5V supply and communicate through an  
I2C Interface. The LTC2471 is single-ended with a 0V to  
VREF input range and the LTC2473 is differential with a  
VREF input range. Both ADC’s include a 1.25V integrated  
referencewith2ppm/°Cdriftperformanceand0.1%initial  
accuracy. The converters are available in a 12-pin DFN  
3mm × 3mm package or an MSOP-12 package. They  
include an integrated oscillator and perform conver-  
sions with no latency for multiplexed applications. The  
LTC2471/LTC2473 include a proprietary input sampling  
scheme that reduces the average input current several  
orders of magnitude when compared to conventional  
delta sigma converters.

Packages  
Following a single conversion, the LTC2471/LTC2473  
automatically power down the converter and can also be  
configured to power down the reference. When both the  
ADC and reference are powered down, the supply current  
is reduced to 200nA.

Instrumentation  
The LTC2471/LTC2473 include a user selectable 250sps  
or 1ksps output rate and due to a large oversampling  
ratio (8,192 at 250sps and 2,048 at 1ksps) have relaxed  
anti-aliasing requirements.
