Detailed Description
The MAX4706/MAX4707 SPST switches operate from a
single supply ranging from 1.8V to 5.5V. The MAX4706
is a normally closed (NC) switch and the MAX4707 is
the normally open (NO) version. These switches provide
3.5 on-resistance (RON) and 0.9 RON flatness with a
+2.7V supply. These devices typically consume only
0.02A of quiescent current, making them suitable for
use in low-power, portable applications. The
MAX4706/MAX4707 feature low-leakage currents over
the entire temperature range, TTL/CMOS-compatible
digital logic, and excellent AC characteristics.
The MAX4706/MAX4707 are offered in small 5-pin and
6-pin SC70 and 6-pin DFN packages.
Applications Information
The MAX4706/MAX4707 operate from a single +1.8V to
+5.5V supply. The MAX4706/MAX4707 accept bipolar
input signals when V+ and GND are biased from bipolar
supplies. For example, the switch accepts a 1VP-P input
when V+ = 2V and GND = -2V. ESD-protection diodes
are internally connected between each analog switch
terminal and both V+ and GND. One of these diodes
conducts if any analog signal is greater than V+ or less
than GND (Figure 1). Virtually all analog leakage current
is attributed to the ESD diodes. Each diode is biased by
the analog signal and either V+ or GND. The ESD
diodes’ leakage currents vary as the signal changes.
Power-Supply Sequencing and
Overvoltage Protection
Caution: Do not exceed the absolute maximum
ratings because stresses beyond the listed ratings
may cause permanent damage to the device.
Proper power-supply sequencing is recommended for
all CMOS devices. Always apply V+ before applying
analog signals, especially if the analog signal is not
current-limited.
