LTC2450CDC-1#TRMPBF

LTC2450CDC-1#TRMPBF is a low-power, ultra-tiny 16bit analogue-to-digital converter designed for space-constrained applications requiring 16bit performance. The LTC2450-1 uses a single 2.7V to 5.5V supply, accepts a single-ended analogue input voltage, and communicates through an SPI interface. It includes an integrated oscillator that does not require any external components. The delta-sigma modulator converter core provides a single-cycle settling time for multiplexed applications. The LTC2450-1 implements a proprietary input sampling scheme that reduces the average input sampling current by several orders of magnitude. It is capable of up to 60 conversions per second and, due to the very large oversampling ratio, has extremely relaxed antialiasing requirements. Applications include system monitoring, environmental monitoring, direct temperature measurements, instrumentation, industrial process control, data acquisition, and embedded ADC upgrades.
