Packages Applications The LTC®2460/LTC2462 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 SPI Interface. The LTC2460 is single-ended
with a 0V to VREF input range and the LTC2462 is differential with a ±VREF input range. Both ADC’s include
a 1.25V integrated reference with 2ppm/°C drift performance and 0.1% initial accuracy. The converters are …
