LTC2451ITS8#TRPBF

LTC®2451 is an Ultra-Tiny, 16bit ∆∑ ADC with I²C Interface. It uses a single 2.7V to 5.5V supply, accepts a single-ended analogue input voltage and communicates through an I²C interface. It includes an integrated oscillator that does not require any external components. It uses a delta-sigma modulator as a converter core and provides single-cycle settling time for multiplexed applications. This includes a proprietary input sampling scheme that reduces the average input sampling current several orders of magnitude lower than conventional ∆∑ converters. It is capable of upto 60 conversions per second and, due to the very large oversampling ratio, has extremely relaxed antialiasing requirements. Application includes system monitoring, environmental monitoring, direct temperature measurements, instrumentation, industrial process control, data acquisition, embedded ADC upgrades.
