GENERAL DESCRIPTION
The ADG790 is a single-chip, CMOS switching solution that
comprises four SPDT switches and two 4:1 multiplexers. The
internal architecture of the device provides two switching
sections, a wide bandwidth section and a low distortion section.
The wide bandwidth section contains three SPDT switches that
exhibit low on resistance with excellent flatness and channel
matching. This, combined with wide bandwidth, makes the
three-SPDT-switch configuration ideal for high frequency
signals, such as full speed (12 Mbps) and high speed (480 Mbps)
USB signals and high resolution video signals.
The low distortion section contains a single SPDT switch and
two 4:1 multiplexers that exhibit very low on resistance and
excellent flatness, making these switches ideal for a wide range
of applications, including low distortion audio applications and
low resolution video (CVBS and S-Video) applications.
When on, all switches conduct equally well in both directions.
When off, all switches block signals up to the supply rails. A
4-wire parallel interface controls the operation of the device
and allows the user to control switches from both sections
simultaneously. This simplifies the design and provides a cost-
effective, single-chip switching solution for portable devices
where multiple signals share a single port connector. The
shutdown (S/D) pin allows all four SPDT switches to be
disabled and forces the 4:1 multiplexers into the S5B and S6B
positions, respectively.
The ADG790 is packaged in a compact, 30-ball WLCSP (6 × 5
ball array) with a total area of 7.5 mm2 (3 mm × 2.5 mm). This
tiny package size and its low power consumption make the
ADG790 an ideal solution for portable devices.
