The LTC2460 family includes single-ended and differential input options. The internal reference voltage for all four of these ADCs is 1.25V. Operating from a single 2.7V to 5.5V supply, the LTC2460 and LTC2461 measure an analog input voltage from 0V to 1.25V. The LTC2462 and LTC2463 measure a ±1.25V analog input. For those applications that require an input range greater than 1.25V, the LTC2450 family can be used with an external reference.
