CS5560DS713PP2 135/4/092. OVERVIEWThe CS5560 is a 24-bit analog-to-digital converter capable of 50 kSps conversion rate. The device is ca-pable of sw

CS556014 DS713PP25/4/09To perform only one conversion, CONV should return high at least 20 master clock cycles before RDYfalls.Once a conversion is co

CS5560DS713PP2 155/4/093.2 ClockThe CS5560 can be operated from its internal oscillator or from an external master clock. The state ofMCLK determines

CS556016 DS713PP25/4/093.4 Analog InputThe analog input of the converter is fully differential with a peak-to-peak input of 4.096 volts on each input
