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 communicate 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...
