Application Information
Often it is desirable to buffer the Hl-524 output, to avoid
loading errors due to the channel “ON” resistance:
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 voltage due to the buffer's bias
currents.
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 (0.1
μ
F to 1
μ
F) 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.
