The LTC2452ITS8#TRMPBF is an ultra-tiny fully differential 16-bit Analog-to-digital Converter (ADC) includes an integrated oscillator that does not require any external components. It uses a delta-sigma modulator as a converter core and has no latency for multiplexed applications. The ADC includes a proprietary input sampling scheme that reduces the average input sampling current several orders of magnitude when compared to conventional delta-sigma converters. Additionally, due to its architecture, there is negligible current leakage between the input pins. It can sample at 60 conversions per second and due to the very large over sampling ratio, has extremely relaxed anti-aliasing requirements. The ADC includes continuous internal offset and full-scale calibration algorithms which are transparent to the user, ensuring accuracy over time and over the operating temperature range. The converter has an external REF pin and the differential input voltage range can extend up to ±VREF.
