    DescripTion

    The LT®6657 is a precision voltage reference that combines robust operating characteristics with extremely low drift and low noise. With advanced curvature compensation, this bandgap reference achieves 1.5ppm/°C drift with predictable temperature behavior, and an initial voltage accuracy of 0.1%. It also offers 0.5ppmP-P noise and very low temperature cycling hysteresis.

    The LT6657 is a low dropout reference that can be powered from as little as 50mV above the output voltage, up to 40V. The buffered output supports ±10mA of output drive with low output impedance and precise load regulation. The high sink current capability allows operation as a negative voltage reference with the same precision as a positive reference. This part is safe under reverse battery condi tions, and includes current protection when the output is short-circuited and thermal shutdown for overload condi tions. A shutdown is included to allow power reduction while enabling a quick turn-on.

    The LT6657 is fully specified over the temperature range of –40°C to 125°C. It is available in the 8-lead MSOP package.

    Drawing

    suggests that in a series of 10 second output voltage measurements, at least half the observations should have a peak-to-peak value that is below this number. For example, the LT6657-2.5 measures less than 0.5ppmP-P in at least 50% of the 10 second observations. As mentioned above, the statistical distribution of noise is such that if observed for long periods of time, the peak error in output voltage due to noise may be much larger than that observed in a smaller interval. The likely maxi mum error due to noise is often estimated using the RMS value, multiplied by an estimated crest factor, assumed to be in the range of 6 to 8.4. This maximum possible value will only be observed if the output voltage is measured for very long periods of time. Therefore, in addition to the common method, a more thorough approach to measuring noise has been used for the LT6657 (described in detail in Linear Technology’s AN124) that allows more information to be obtained from the result. In particular, this method characterizes the noise over a significantly greater length of time, resulting in a more complete description of low frequency noise. The reference noise is measured at the output of the circuit shown in Figure 15 with an ADC/DVM system. Peak-to-peak voltage is then calculated for 10
