The LTC2450-1 is a low power, ultra-tiny 16-bit analogto-digital converter designed for space constrained applications requiring 16-bit performance. The LTC2450-1 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. The delta-sigma modulator converter core provides single-cycle settling time for multiplexed applications. The converter is available in a 6-pin, 2mm x 2mm DFN package. The LTC2450-1 implements a proprietary input sampling scheme that reduces the average input sampling current several orders of magnitude.
