Figure 13. Using the AD660 with the AD688 High Precision ±10 V Reference
OUTPUT SETTLING AND GLITCH
The AD660 output buffer amplifier typically settles to within
0.0008% FS (1/2 LSB) of its final value in 8 μs for a full-scale
step. Figure 14 and Figure 15 show settling for a full-scale and
an LSB step, respectively, with a 2 kΩ, 1000 pF load applied.
The guaranteed maximum settling time at 25°C for a full-scale
step is 13 μs with this load. The typical settling time for a 1 LSB
step is 2.5 μs.
The digital-to-analog glitch impulse is specified as 15 nV-s
typical. Figure 16 shows the typical glitch impulse characteristic
at the 011…111 to 100…000 code transition when loading the
second rank register from the first rank register.
