GENERAL DESCRIPTION
The ADV3219 and ADV3220 are high speed, high slew rate,
buffered, 2:1 analog multiplexers. They offer a −3 dB signal
bandwidth greater than 800 MHz and channel switch times of
less than 20 ns with 1% settling. With −82 dB of crosstalk and
−88 dB isolation (at 5 MHz), the ADV3219 and ADV3220 are
useful in many high speed applications. The differential gain of
less than 0.02% and the differential phase of less than 0.02°,
together with 0.1 dB flatness beyond 100 MHz while driving a
75 Ω back terminated load, make the ADV3219 and ADV3220
ideal for all types of signal switching.

Figure 1.
The ADV3219/ADV3220 include an output buffer that can be
placed into a high impedance state to allow multiple outputs to
be connected together for cascading stages without the off channels
loading the output bus. The ADV3219 has a gain of +1, and the
ADV3220 has a gain of +2; they both operate on ±5 V supplies
while consuming less than 7.5 mA of idle current.
The ADV3219/ADV3220 are available in the 8-lead LFCSP
package over the extended industrial temperature range of
−40°C to +85°C.

Stresses at or above those listed under Absolute Maximum
Ratings may cause permanent damage to the product. This is a
stress rating only; functional operation of the product at these
or any other conditions above those indicated in the operational
section of this specification is not implied. Operation beyond
the maximum operating conditions for extended periods may
affect product reliability.
THERMAL RESISTANCE
θJA is specified for the worst-case conditions, that is, a device
soldered in a circuit board for surface-mount packages.

POWER DISSIPATION
The ADV3219/ADV3220 are operated with ±5 V supplies and
can drive loads down to 150 Ω, resulting in a wide range of
possible power dissipations. For this reason, extra care must
be taken derating the operating conditions based on ambient
temperature.
Packaged in an 8-lead LFCSP, the ADV3219 and ADV3220
junction-to-ambient thermal impedance (θJA) is 85°C/W. For long-
term reliability, the maximum allowed junction temperature of the
die, TJ, must not exceed 125°C. Temporarily exceeding this limit
can cause a shift in parametric performance due to a change in
stresses exerted on the die by the package. Figure 2 shows the
range of the allowed internal die power dissipations that meet
these conditions over the −40°C to +85°C ambient temperature
range. When using Figure 2, do not include the external load
power in the maximum power calculation, but do include the
load current through the die output transistors.
