GENERAL DESCRIPTION
The ADV3221 and ADV3222 are high speed, high slew rate,
buffered 4:1 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 lower than 58 dB of
crosstalk and 67 dB isolation (at 100 MHz), the ADV3221 and
ADV3222 are useful in many high speed applications. The diffe-
rential gain error of less than 0.02% and differential phase error
of less than 0.02°, together with 0.1 dB gain flatness out to 100 MHz
while driving a 75 Ω back terminated load, make the ADV3221
and ADV3222 ideal for all types of signal switching.
The ADV3221/ADV3222 include an output buffer that can be
placed into a high impedance state. This allows multiple outputs
to be connected together for cascading stages without the off
channels loading the output bus. The ADV3221 has a gain of
+1, and the ADV3222 has a gain of +2; they both operate on ±5 V
supplies while consuming less than 7.5 mA of idle current. The
channel switching is performed via latched control lines, allowing
synchronous updating in a multiple ADV3221/ADV3222 envi-
ronment.
The ADV3221/ADV3222 are offered in a 16-lead SOIC package
and are available over the extended industrial temperature range of
40°C to +85°C.
