NOTES
1
Shutdown (SD) and
ENABLE
pins are grounded (AD8174). IN0 (or IN2) = +0.5 V dc, IN1 (or IN3) = –0.5 V dc. SELECT (A0 or A1 for AD8174) input is
driven with 0 V to +5 V pulse. Measure transition time from 50% of SELECT (A0 or A1) input value (+2.5 V) and 10% (or 90%) of the total output voltage transi-
tion from IN0 (or IN2) channel voltage (+0.5 V) to IN1 (or IN3 = –0.5 V) or vice versa.
2
AD8174 only. Shutdown (SD) pin is grounded.
ENABLE
pin is driven with 0 V to +5 V pulse (5 ns rise and fall times). State of A0 and A1 logic inputs determines
which channel is activated (i.e., if A0 = Logic 0 and A1 = Logic 1, then IN2 input is selected). Set IN0 (or IN2) = +0.5 V dc, IN1 (or IN3) = –0.5 V dc, and mea-
sure transition time from 50% of
ENABLE
pulse (+2.5 V) to 90% of the total output voltage change. In Figure 5,
t
OFF
is the disable time,
t
ON
is the enable time.

AD8174 only.
ENABLE
pin is grounded. Shutdown (SD) pin is driven with 0 V to +5 V pulse (5 ns rise and fall times). State of A0 and A1 logic inputs determines
which channel is activated (i.e., if A0 = Logic 1 and A1 = Logic O, then IN1 input is selected). Set IN0 (or IN2) = +0.5 V dc, IN1 (or IN3) = –0.5 V dc, and mea-
sure transition time from 50% of SD pulse (+2.5 V) to 90% of the total output voltage change. In Figure 6,
t
OFF
is the shutdown assert time,
t
ON
is the shutdown
release time.
4
All inputs are grounded. SELECT (A0 or A1 for AD8174) input is driven with 0 V to +5 V pulse. The outputs are monitored. Speeding the edges of the SELECT
(A0 or A1) pulse increases the glitch magnitude due to coupling via the ground plane.
5
Bandwidth of the multiplexer is dependent upon the resistor feedback network. Refer to Table III for recommended feedback component values, which give the best
compromise between a wide and a flat frequency response.
6
Select input(s) that is (are) not being driven (i.e., if SELECT is Logic 1, activated input is IN1; in AD8174, if A0 = Logic 0, A1 = Logic 1, activated input is IN2).
Drive all other inputs with V
IN
= 0.707 V rms, and monitor output at f = 5 MHz and 30 MHz;
R
L
= 100
(see Figure 13).
7
AD8174 only. Shutdown (SD) pin is grounded. Mux is disabled, (i.e.,
ENABLE
= Logic 1) and all inputs are driven simultaneously with V
IN
= 0.354 V rms. Out-
put is monitored at f = 5 MHz and 30 MHz; R
L
= 100
. In this mode, the output impedance of the disabled mux is very high (typ 10 M
), and the signal couples
across the package; the load impedance and the feedback network determine the crosstalk. For instance, in a closed-loop gain of +1, r
OUT
ù
10 M
, in a gain of +2
(R
F
= R
G
= 549
), r
OUT
= 1.1 k
(see Figure 14).

AD8174 only.
ENABLE
pin is grounded. Mux is shutdown (i.e., SD = Logic 1), and all inputs are driven simultaneously with V
IN
= 0.354 V rms. Output is moni-
tored at f = 5 MHz and 30 MHz;
R
L
= 100
. (see Figure 14). The mux output impedance in shutdown mode is the same as the disabled mux output impedance.

For Gain Accuracy expression, refer to Equation 4.
