Low Voltage, CMOS Multimedia Switch
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.
