The LTC2450-1 is a low power, ultra-tiny 16-bit analog-to-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.

The LTC2450-1 is capable of up to 60 conversions per second and, due to the very large oversampling ratio, has extremely relaxed antialiasing requirements. 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.

Following a conversion, the LTC2450-1 can automatically enter a sleep mode and reduce its power to less than 500nA. At an output rate of 1Hz, the LTC2450-1 consumes an average of less than 25µW from a 2.7V supply.
