ADG790:   Low Voltage, CMOS Multimedia Switch

Product Details


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.
