... The maximum slope of the two diagonals drawn from the initial output value at +25°C to the output values at +85°C and −40°C determines the performance grade of the device. For a given grade of the ADR1581, the designer can easily determine the maximum total error from the initial are at their minimum ...

... This shows the same data in a different format. This characteristic (see Figure 13) is generated by normalizing the measured drift characteristic to the endpoint average drift. The residual drift error of approximately 500 ppm shows that the ADR1581 is compatible with systems that require 10-bit accurate temperature performance. –6 V ...

... NOISE PERFORMANCE AND REDUCTION The noise generated by the ADR1581 is typically less than 5 μV p-p over the 0 band. 0 noise of a typical ADR1581. Noise kHz bandwidth is approximately 20 μV rms (see Figure 17a). If further noise reduction is desired, a one-pole low-pass filter can be added between the output pin and ground. A time constant of 0.2 ms has a − ...

... The circuit in Figure 23 provides an ideal solution for creating a stable voltage reference with low standby power consumption, low input/output dropout capability, and minimum noise output. The amplifier both buffers and optionally scales up the ADR1581 (a) output voltage. Output voltages as high as 2.1 V can supply load current ...

... The ADR1581 low output drift (50 ppm/°C) and compact subminiature SOT-23 package make it ideally suited for today’s high performance converters in space-critical applications. One family of ADCs for which the ADR1581 is well suited is the AD7714-3 and AD7715-3. The AD7714/AD7715 are charge- balancing (∑-Δ) ADCs with on-chip digital filtering intended for ...
