LTC2461CMS#PBF

LTC®2461 is an ultra tiny, 16bit analog-to digital converter with an integrated precision reference. This uses a single 2.7V to 5.5V supply and communicates through an I²C Interface. The LTC2461 is single-ended with a 0V to 1.25V input range and the LTC2463 is differential with a 1.25V input range. This includes an integrated oscillator and perform conversions with no latency for multiplexed applications. This 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, the LTC2461 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. Application includes system monitoring, environmental monitoring, direct temperature measurements, instrumentation, data acquisition, embedded ADC upgrades.
