LTC2450CDC#TRMPBF

LTC®2450 is an ultra-tiny 16bit analogue-to-digital converter. The LTC2450 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. It uses a delta-sigma modulator as a converter core and provides single-cycle settling time for multiplexed applications. The LTC2450 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 uses its power supply voltage as the reference voltage and the single-ended, rail-to-rail input voltage range extends from GND to VCC. Typical applications include system monitoring, environmental monitoring, direct temperature measurements, instrumentation, industrial process control, data acquisition and embedded ADC upgrades.
