MAX4584/MAX4585
_______________Detailed Description
The MAX4584/MAX4585 are serial-interface, program-
mable switches. Each device contains one normally
open (NO) single-pole/single-throw (SPST) switch and
one single-pole/double-throw (SPDT) switch. The
switches are independently controlled through the on-
chip serial interface. The MAX4584 uses a 2-wire I2C-
compatible serial communications protocol; the
MAX4585 uses a 3-wire SPI/QSPI/MICROWIRE-com-
patible serial communications protocol.
These devices operate from a single +2.7V to +5.5V
supply and are optimized for use with an audio fre-
quency of 20kHz and video frequencies up to 10MHz.
They feature 65
on-resistance, 4 on-resistance
matching between channels, and 5
on-resistance flat-
ness. Audio off-isolation is -83dB at 20kHz, and
crosstalk is at least -84dB at 20kHz. Video off-isolation
is -48dB at 10MHz, and crosstalk is at least -60dB at
10MHz.
__________Applications Information
Switch Control
The MAX4584/MAX4585 have a common command-bit
structure; the only difference between them is the inter-
face type (2-wire or 3-wire, respectively).
The command controls the open/closed states of the
various switches. Table 1 shows the configuration of
the data bits and their related switches. After a com-
mand is issued, a logic “1” in any data-bit location clos-
