Application Information
Often it is desirable to buffer the Hl-524 output, to avoid loading
errors due to the channel “ON” resistance:
HA-524
CH1
75
HA-2541
+
12
Note that the on-chip feedback element between pins 16 and
18 includes two switches in series, to simulate a channel
resistance. These switches open for V
EN
= Low. This allows
two or more Hl-524s to operate into one HA-2541, with their
feedback elements connected in parallel. Thus, only the
selected multiplexer provides feedback, and the amplifier
remains stable.
All Hl-524 pins labeled ‘SlG GND’ (pins 3, 4, 6, 13, 15) should
be externally connected to signal ground for best crosstalk
performance.
Bypass capacitors (0.1F to 1F) are recommended from each
HI-524 supply pin to power ground (pins 1 and 17 to pin 8).
Locate the buffer amplifier near the Hl-524 so the two
capacitors may bypass both devices.
If an analog input 1V or greater is present when supplies are
off, a low resistance is seen from that input to a supply line.
(For example, the resistance is approximately 160 for an
input of -3V.) Current flow may be blocked by a diode in each
supply line, or limited by a resistor in series with each channel.
The best solution, of course, is to arrange that no digital or
analog inputs are present when the power supplies are off.

FIGURE 5.
The buffer amplifier should offer sufficient bandwidth and slew
rate to avoid degradation of the anticipated signals. For video
switching, the HA-5033 and HA-2542 offer good performance
plus
100mA
output current for driving coaxial cables. For
general wideband applications, the HA-2541 offers the
convenience of unity gain stability plus 90ns settling (to
0.1%)
and
10V
output swing. Also, the Hl-524 includes a feedback
resistance for use with the HA-2541. This resistance matches
and tracks the channel “ON” resistance, to minimize offset
