Product Summary

The LTC2452ITS8#TRPBF is an Analog to Digital Converter. The LTC2452ITS8#TRPBF is an ultra-tiny, fully differential, 16-bit, analog-to-digital converter. The LTC2452ITS8#TRPBF uses a single 2.7V to 5.5V supply and communicates through an SPI interface. The ADC is available in an 8-pin, 3mm × 2mm DFN package or TSOT-23 package. It includes an integrated oscillator that does not require any external components. It uses a delta-sigma modulator as a converter core and has no latency for multiplexed applications. The LTC2452ITS8#TRPBF includes a proprietary input sampling scheme that reduces the average input sampling current several orders of magnitude when compared to conventional delta-sigma converters. Additionally, due to its architecture, there is negligible current leakage between the input pins. The LTC2452ITS8#TRPBF can sample at 60 conversions per second, and due to the very large oversampling ratio, has extremely relaxed antialiasing requirements. The LTC2452ITS8#TRPBF includes continuous internal offset and full-scale calibration algorithms which are transparent to the user, ensuring accuracy over time and over the operating temperature range. The converter has an external REF pin and the differential input voltage range can extend up to ±VREF. The applications of the LTC2452ITS8#TRPBF include System Monitoring, Environmental Monitoring, Direct Temperature Measurements, Instrumentation, Industrial Process Control, Data Acquisition and Embedded ADC Upgrades.
