LTC2463IDD#PBF

LTC2463IDD#PBF is a 16bit analogue-to-digital converter with an integrated precision reference. It uses a single 2.7V to 5.5V supply and communicates through an I²C Interface. The LTC2463 is differential with a 1.25V input range. This ADC includes a 1.25V integrated reference with 2ppm/°C drift performance and 0.1% initial accuracy. It includes an integrated oscillator and performs conversions with no latency for multiplexed applications. It includes a proprietary input sampling scheme that reduces the average input current by several orders of magnitude when compared to conventional delta-sigma converters. It can sample at 60 conversions per second and, due to the very large oversampling ratio, has extremely relaxed antialiasing requirements. Applications include system monitoring, environmental monitoring, direct temperature measurements, instrumentation, data acquisition, and embedded ADC upgrades.
