FEATURES  
DESCRIPTIO  
The LTC®2404/LTC2408 are 4-/8-channel 2.7V to 5.5V  
micropower 24-bit A/D converters with an integrated  
oscillator, 4ppm INL and 0.3ppm RMS noise. They use  
delta-sigma technology and provide single cycle digital  
filter settling time (no latency delay) for multiplexed  
applications. The first conversion after the channel is  
changedisalwaysvalid.ThroughasinglepintheLTC2404/  
LTC2408 can be configured for better than 110dB rejec-  
tion at 50Hz or 60Hz ±2%, or can be driven by an external  
oscillator for a user defined rejection frequency in the  
range 1Hz to 120Hz. The internal oscillator requires no  
external frequency setting components.
