The LTC2410 is a 2.7V to 5.5V micropower 24-bit differential ∆Σ analog to digital converter with an integrated oscillator, 2ppm INL and 0.16ppm RMS noise. It uses delta-sigma technology and provides single cycle settling time for multiplexed applications. Through a single pin, the LTC2410 can be configured for better than 110dB input differential mode rejection at 50Hz or 60Hz ±2%, or it can be driven by an external oscillator for a user defined rejection frequency. The internal oscillator requires no external frequency setting components.The converter accepts any external differential reference voltage from 0.1V to VCCfor flexible ratiometric and remote sensing measurement configurations. The full-scale differential input range is from –0.5VREFto 0.5VREF. The reference common mode voltage, VREFCM, and the input common mode voltage, VINCM, may be independently set anywhere within the GND to VCCrange of the LTC2410. The DC common mode input rejection is better than 140dB.The LTC2410 communicates through a flexible 3-wire digital interface which is compatible with SPI and MICROWIRE protocols.ApplicationsDirect Sensor DigitizerWeight ScalesDirect Temperature MeasurementGas AnalyzersStrain-Gauge TransducersInstrumentationData AcquisitionIndustrial Process Control6-Digit DVMs
