LTC2450 Easy-to-Use, Ultra-Tiny 16-Bit ΔΣ ADC DESCRIPTION The LTC®2450 is an ultra-tiny 16-bit analog-to-digital converter. The LTC2450 uses a single 2.7V to 5.5V supply, accepts a single-ended analog 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 converter is available in a 6-pin, 2mm × 2mm DFN package. The internal oscillator does not require any ex...
