When LE is connected to ground, the E—Nregister is
transparent and independent of C—activity. This allows
all MAX463–MAX466 devices to be simultaneously shut
LE to ground and connect all E—–inputs together (Figure
5a). For the MAX464 and MAX466, LE must be hard-
wired to either V+ or ground (rather than driving LE with
a gate) to prevent crosstalk from the digital inputs to
IN0A.
Another option for output disable is to connect LE to V+,
parallel the outputs of several MAX463-MAX466s, and use
(Figure 5b).
When the outputs are disabled, the off isolation from
the analog inputs to the amplifier outputs is typically
70dB at 10MHz, all inputs driven with a 4V
P-P
sine
wave and a 150
load impedance. Figure 6 shows the
test circuits used to measure isolation and crosstalk.
