Overview

The LTC2451CDDB is an ultra-tiny, 16-bit, analog-to-digital converter. The LTC2451CDDB uses a single 2.7V to 5.5V supply, accepts a single-ended analog input voltage and communicates through an I2C interface. The converter is available in an 8-pin, 3mm × 2mm DFN or TSOT-23 package. 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 LTC2451CDDB includes a proprietary input sampling scheme that reduces the average input sampling current several orders of magnitude lower than conventional ΔΣ converters.

Following a single conversion, the LTC2451CDDB can automatically enter sleep mode and reduce its power to less than 0.2μA. If the user reads the ADC once per second, the LTC2451CDDB consumes an average of less than 50μW from a 2.7V supply.
