To illustrate the outstanding performance of the LTC6655, consider that a typical low noise voltage reference would offer 2ppm or less of low frequency noise. For a 2.5V output voltage, 2ppm corresponds to 5µV of noise, as compared to only 0.6µV from the LTC6655. Similarly, a typical precision voltage reference would offer 5ppm/°C or less of temperature drift. The LTC6655 has a temperature drift of only 2ppm/°C.
