Product Overview

The LTC2451CDDB#TRMPBF is an ultra-tiny 16-bit Analog-to-digital Converter (ADC) accepts a single-ended analog input voltage and communicates through an I²C 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 ADC includes a proprietary input sampling scheme that reduces the average input sampling current several orders of magnitude lower than conventional delta-sigma converter. The ADC is capable of up to 60 conversions per second and, due to the very large oversampling ratio, has extremely relaxed anti-aliasing requirements. In the 30Hz mode, the ADC includes continuous internal offset calibration algorithms which are transparent to the user, ensuring accuracy over time and over the operating temperature range. The converter has external REF+ and REF- pins and the input voltage can range from VREF- to VREF+.
  • GND to VCC single-ended input range
  • Single conversion settling time
  • Single-cycle operation with auto shutdown
  • Internal oscillator - no external components required
  • 2-wire I²C interface
