Ultra Low ON-Resistance, Low Voltage,
Single Supply, Quad SPDT (Dual DPDT)
Analog Switch
The Intersil ISL83699 device is a low ON-resistance, low
voltage, bidirectional, Quad SPDT (Dual DPDT) analog
switch designed to operate from a single +1.65V to +3.6V
supply. Targeted applications include battery powered
equipment that benefit from low on-resistance (0.26), and
fast switching speeds (tON = 10ns, tOFF = 7ns). The digital
logic input is 1.8V logic-compatible when using a single +3V
supply.
Cell phones, for example, often face ASIC functionality
limitations. The number of analog input or GPIO pins may be
limited and digital geometries are not well suited to analog
switch performance. This family of parts may be used to
“mux-in” additional functionality while reducing ASIC design
risk. The ISL83699 is offered in small form factor packages,
alleviating board space limitations.
The ISL83699 consists of four SPDT switches. It is configured
as a dual double-pole/double-throw (DPDT) device with two
logic control inputs that control two SPDT switches each. The
configuration can be used as a dual differential 2-to-1
multiplexer/demultiplexer. The ISL83699 is pin compatible
with the STG3699.

Leakage Considerations
Reverse ESD protection diodes are internally connected
between each analog-signal pin and both V+ and GND. One of
these diodes conducts if any analog signal exceeds V+ or
GND.
Virtually all the analog leakage current comes from the ESD
diodes to V+ or GND. Although the ESD diodes on a given
signal pin are identical and therefore fairly well balanced,
they are reverse biased differently. Each is biased by either
V+ or GND and the analog signal. This means their leakages
will vary as the signal varies. The difference in the two diode
leakages to the V+ and GND pins constitutes the analog-
signal-path leakage current. All analog leakage current flows
between each pin and one of the supply terminals, not to the
other switch terminal. This is why both sides of a given
switch can show leakage currents of the same or opposite
polarity. There is no connection between the analog signal
paths and V+ or GND.
