MAX458/MAX459
Driving Capacitive Loads
When driving loads greater than 100pF, you may need
a capacitance compensating resistor in series with the
output of each affected amplifier. The required resistor
will depend on load as well as capacitance. For 150
or higher load resistances and capacitance up to
1000pF, use a 2.4
resistor. For 100 loads, use a
4.7
resistor.
If an output amplifier is loaded with a pure capacitance
or with the inputs of other MAX458/MAX459s, the resis-
tors will cause no degradation of gain or other perfor-
mance because of the high impedance of the
crosspoints. However, resistive loads may cause a
reduction in gain.
Daisy-Chaining Devices
The serial output, DOUT, allows cascading of two or
more crosspoint switches to create larger arrays. The
data at DOUT is the DIN data delayed by 16 cycles
plus one clock width. DOUT changes on SCLK’s falling
edge when
–
C
—
S
–
is low. When C
—
S
–
is high, DOUT remains
in the state of the last data bit.
Any number of MAX458/MAX459 crosspoint switches
can be daisy-chained by connecting the DOUT of one
device to the DIN of the next device in the chain, as
shown in Figure 12. For proper timing, ensure that both
tCSS (C
—
S
–
low to SCLK high) and tCL are greater than
tDO + tDS.
DOUT is a TTL-compatible output with an active pull-
up. It does not become high impedance when C
—
S
–
is
high.
