LTC2452ITS8#TRMPBF

LTC®2452 is an ultra-tiny, fully differential, 16bit, analogue-to-digital converter. The LTC2452 uses a single 2.7V to 5.5V supply and communicates through an SPI interface. 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 LTC2452 includes a proprietary input sampling scheme that reduces the average input sampling current by 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. Typical applications include system monitoring, environmental monitoring, direct temperature measurements, instrumentation, industrial process control, data acquisition and embedded ADC upgrades.
