MAX4550/MAX4570
The MAX4550/MAX4570 serial-interface, programma-
ble, dual 4x2 audio/video crosspoint switches are ideal
for multimedia applications. Each device contains two
identical crosspoint switch arrays, each with four inputs
and two outputs. To improve off-isolation, use the addi-
tional crosspoint inputs SA and SB as shunts. Each out-
put is selectively programmable for clickless or regular
mode operation. A set of internal resistive voltage-
dividers supplies DC bias for each output when using
AC-coupled inputs. Additionally, four auxiliary outputs
control additional circuitry via the MAX4550/MAX4570’s
2-wire or 3-wire interface.
The MAX4550/MAX4570 feature 80Ω on-resistance, 10Ω
on-resistance matching between channels, 5Ω on-
resistance flatness, and 0.014% total harmonic distor-
tion. Additionally, they feature off-isolation of at least
-110dB in the audio frequency range and -78dB at
4MHz, with -95dB crosstalk in the audio frequency
range and -54dB at 4MHz. The MAX4550 uses a 2-wire
I
2
C-compatible serial interface, while the MAX4570
uses a 3-wire SPI™/QSPI™ or MICROWIRE™-compati-
ble serial interface. These parts are available in 28-pin
SSOP and wide SO packages and are tested over
either the commercial (0°C to +70°C) or extended
(-40°C to +85°C) operating temperature range.
