LTC2463IMS#PBF

LTC2463IMS#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. This device is differential with a 1.25V input range. 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. Following a single conversion, this device automatically powers 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, data acquisition, and embedded ADC upgrades.
