The LTC2452CTS8#TRMPBF is a differential 16-bit delta-sigma A/D Converter with SPI interface. It includes an integrated oscillator that does not require any external components. It uses a ΔΣ modulator as a converter core and has no latency for multiplexed applications. The LTC2452 includes a proprietary input sampling scheme that reduces average input sampling current several orders of magnitude when compared to conventional delta-sigma converters. Due to its architecture, there is negligible current leakage between the input pins. The LTC2452 can sample at 60 conversions per second and due to the very large oversampling ratio, has extremely relaxed anti-aliasing requirements. It 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 differential input voltage range can extend up to ±VREF.
