Description

The LTC2435CGN is 2.7V to 5.5V micropower 20-bit differential analog to digital converters with combined oscillator, 3ppm INL and 0.8ppm RMS noise. It is a delta-sigma technology and offering single cycle settling time for multiplexed applications, the LTC2435CGN  is bale to be configured for better than 110 dB input differential mode rejection at 50Hz or 60Hz±2% , or it can be driven by an external oscillator for a user defined rejection frequency via a single pin.

Features of the  LTC2435CGN are:(1)2* speed up version of the LTC2430: 15Hz output rate, 60Hz notch-LTC2435; 13.75Hz output rate,simultaneous 50H z/60Hz notch-LTC2435-1;(2)differential input and differential reference with GND to VCC common mode range;(3)3ppm INL, no missing codes;(4)10ppm gain error;(5):0.8ppm noise;(6)single conversion settling time for multiplexed applications;(7)internal oscillator-no external components required;(8)single supply 2.7V to 5.5V operation.

The absolute maximum ratings and electrical characteristics(TA = + 25°C)of the LTC2435CGN can be summarized as:(1):supply voltage (VCC) to GND is0.3 V to 7V;(2):analog input pins voltage to GND is0.3V to (VCC + 0.3V):(3):reference input pins voltage to GND is 0.3V to (VCC + 0.3V);(4):digital input volta ge to GND is0.3V to (VCC + 0.3V);(5):digital output voltage to GND is0.3V to (VCC + 0.3V);(6):operating temperature ranges from  0°C to 70°C;(7): storage temperature ranges  from65°C to 150°C;(8):lead temperature (soldering, 10 sec) is 300°C.Electrical characteristics:(1):resolution is 20Bits min(0.1V VREF VCC, 0.5 • VREF VIN 0.5 • VREF);(2):output noise is 4 µVRMS typ(5V VCC 5.5V, REF+ = 5V, REF = GND,GND IN = IN+ VC C);(3):offset error is 2mV typ and 5mV max(2.5V REF+ VCC, REF = GND, GND  IN+ = IN VCC).etc.
