GENERAL DESCRIPTION
The ADG738 and ADG739 are CMOS analog matrix switches with a serially-controlled 3-wire interface. The ADG738 is an 8-channel matrix switch, while the ADG739 is a dual 4-channel matrix switch. On resistance is closely matched between switches and very flat over the full signal range.
FUNCTIONAL BLOCK DIAGRAMS
Figure 1.
Figure 2.
The ADG738 and ADG739 utilize a 3-wire serial interface that is
compatible with SPI™, QSPI™, MICROWIRE®, and some DSP interface
standards. The output of the input shift register, DOUT, enables a
number of these parts to be daisy-chained. On power-up, the
internal input shift register contains all zeros and all switches
are in the off state. Each switch conducts equally well in both
directions when on, making these parts suitable for both
multiplexing and demultiplexing applications. As each switch is
turned on or off by a separate bit, these parts can also be
configured as a type of switch array, where any, all, or none of
the eight switches may be closed at any time. The input signal
range extends to the supply rails.
All channels exhibit break-before-make switching action, preventing
momentary shorting when switching channels. The ADG738 and ADG739
are available in 16-lead TSSOP packages.
