Measuring Settling Time
Settling time is measured as follows. The relationship
between V and V
0(FS)
as shown in the D/A output waveform
in Figure 12 is expressed as
V = V
0(FS)
(1 - e
-t
τ
).
The settling time for respective accuracy of 10, 9 and 8-bit is
specified as
V = 0.9995 V
0(FS)
V = 0.999 V
0(FS)
V = 0.999 V
0(FS)
which results in the following:
t
S
= 7.60

Rise time (t
r
) and fall time (t
f
) are defined as the time interval
to slew from 10% to 90% of full scale voltage (V
0(FS)
):
V = 0.1 V
0(FS)
V = 0.9 V
0(FS)
and calculated as t
r
= t
f
= 2.20
τ
.
The settling time is obtained by combining these expressions:
for 10-bit,
for 9-bit, and
for 8-bit,
t
S
= 3.45t
r
t
S
= 3.15t
r

= 6.24t
r
for 10-bit,
for 9-bit, and
for 8-bit
