FEATURES  
DESCRIPTIO  
The LTC®2444/LTC2445/LTC2448/LTC2449 are 8-/16-  
channel (4-/8-differential) high speed 24-bit No Latency  
∆ΣTM ADCs. They use a proprietary delta-sigma architec-  
ture enabling variable speed/resolution. Through a simple  
4-wire serial interface, ten speed/resolution combinations  
6.9Hz/280nVRMS to 3.5kHz/25µVRMS (4kHz with external  
oscillator) can be selected with no latency between con-  
version results or shift in DC accuracy (offset, full-scale,  
linearity, drift). Additionally, a 2X speed mode can be  
selected enabling output rates up to 7kHz (8kHz if an  
external oscillator is used) with one cycle latency.

■
Autosleep Enables 20µA Operation at 6.9Hz  
■
<5µV Offset (4.5V < VCC < 5.5V, –40°C to 85°C)  
Any combination of single-ended or differential inputs can  
beselectedwithacommonmodeinputrangefromground  
to VCC, independent of VREF. While operating in the 1X  
speed mode the first conversion following a new speed,  
resolution, or channel selection is valid. Since there is no  
settling time between conversions, all 8 differential chan-  
nels can be scanned at a rate of 500Hz. At the conclusion  
of each conversion, the converter is internally reset elimi-  
nating any memory effects between successive conver-  
sions and assuring stability of the high order delta-sigma  
modulator.
