FEATURES  
DESCRIPTIO  
16-Bit Differential ADC in a Tiny MSOP  
The LTC®2433-1 is a differential input micropower 16-bit  
No Latency ∆ΣTM analog-to-digital converter with an inte-  
grated oscillator. It provides 0.12LSB INL and 1.45µV  
RMS noise independent of VREF. It uses delta-sigma  
technology and provides single conversion settling of the  
digital filter. Through a single pin, the LTC2433-1 can be  
configured for better than 87dB input differential mode  
rejection at 50Hz and 60Hz ±2%, or it can be driven by an  
external oscillator for a user defined rejection frequency.  
The internal oscillator requires no external frequency  
setting components.  
Low Supply Current: 200µA, 4µA in Autosleep  
Rail-to-Rail Differential Input/Reference  
0.12LSB INL, No Missing Codes  
0.16LSB Full-Scale Error and 5  
µV Offset  
1.45µV RMS Noise, Independent of VREF  
Very Low Transition Noise: <0.02LSB  
Operates with a Reference as Low as 100mV with  
16-Bit Resolution  
Internal Oscillator—No External Components  
Required  
87dB Min, Simultaneous 50Hz and 60Hz Notch Filter  
Single Supply 2.7V to 5.5V Operation  
Pin Compatible with the 20/24-Bit LTC2431/LTC2411  
Available in 10-Lead MSOP Package  
The converter accepts any external differential reference  
voltage from 0.1V to VCC for flexible ratiometric and  
remote sensing measurement configurations. The full-  
scale differential input range is from 0.5 • VREF to 0.5 •  
VREF. The reference common mode voltage, VREFCM, and  
the input common mode voltage, VINCM, may be indepen-  
dently set anywhere between GND and VCC. The DC  
common mode input rejection is better than 140dB.
