LTC2461/LTC2463 Ultra-Tiny, 16-Bit I2C ΔΣ ADCs with 10ppm/°C Max Precision Reference DESCRIPTION The LTC®2461/LTC2463 are ultra tiny, 16-Bit analog-todigital converters with an integrated precision reference. They use a single 2.7V to 5.5V supply and municate 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. Both ADCs include a 1.25V integrated reference with 2ppm/°C drift performance and 0.1% initial accuracy. The converters are available in a 12-pin 3mm × 3mm DFN package or an MSOP-12 package. They include an integrated oscillator and perform conversions with no latency for multiplexed applications. The LTC2461/LTC2463 include a proprietary input sampling scheme that reduces the average input current several orders of magnitude when pared to conventional delta sigma converters. Following a single conversion, the LTC2461/LTC2463 automatically power down the converter and can also be configured to power down the reference. When...
