LTC2460CMS#PBF

LTC2460CMS#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 SPI Interface. This ADC includes a 1.25V integrated reference with 2ppm/°C drift performance and 0.1% initial accuracy. It includes an integrated oscillator and perform conversions with no latency for multiplexed applications. It includes a proprietary input sampling scheme that reduces the average input current several orders of magnitude when compared to conventional delta-sigma converters. Following a single conversion, this device automatically power down the converter and can also be configured to power down the reference. When both the ADC and reference are powered down, the supply current is reduced to 200nA. Applications include system monitoring, environmental monitoring, direct temperature measurements, instrumentation, industrial process control, data acquisition, and embedded ADC upgrades.
