GENERAL DESCRIPTION
The ADG714/ADG715 are CMOS, octal SPST (single-pole,
single-throw) switches controlled via either a 2- or 3-wire serial
interface. On resistance is closely matched between switches and
very flat over the full signal range. Each switch conducts equally
well in both directions and the input signal range extends to the
supplies. Data is written to these devices in the form of 8 bits,
each bit corresponding to one channel.
The ADG714 uses a 3-wire serial interface that is compatible
with SPI
, QSPI,
and MICROWIRE
and most DSP interface
standards. The output of the shift register DOUT enables a
number of these parts to be daisy chained.
The ADG715 uses a 2-wire serial interface that is compatible
with the I
2
C interface standard. The ADG715 has four hard wired
addresses, selectable from two external address pins (A0 and A1).
This allows the 2 LSBs of the 7-bit slave address to be set by
the user. A maximum of four of these devices may be connected
to the bus.
On power-up of these devices, all switches are in the OFF con-
dition, and the internal registers contain all zeros.
Low power consumption and operating supply range of 2.7 V to
5.5 V make this part ideal for many applications. These parts
may also be supplied from a dual ± 2.5 V supply. The ADG714
and ADG715 are available in a small 24-lead TSSOP package.
