Low-Voltage, Dual SPDT, Audio Clickless Switches with
Negative Rail Capability

Datasheet
1 General Description
The SPDT (single-pole/double-throw) switches AS1747,
AS1748, AS1749 and AS1750 allow signals below
ground to pass through without distortion. These analog
switches are ideal for switching audio signals, due to
their supply voltage from +1.8V to +5.5V and their low
0.4Ω on-resistance.
An included comparator offers the AS1748 and AS1750
with headphone detection or mute/send key function.
To reduce click-and-pop sounds when switching
between pre-charged points the AS1749 and AS1750
have an internal shunt switch. This shunt switch auto-
matically discharges any capacitance at the NO and NC
connection points.
This SPDT switch is available in space-saving 10-pin
TDFN 3x3 packages and operate over the -40ºC to
+85ºC extended temperature range.

8 Detailed Description
The AS1747– AS1750 are operating from a +1.8V to +5.5V supply and feature a negative signal capability that allows
signals below ground to pass through without distortion. A break-before-make switching and a low on-resistance are
also included in this analog dual SPDT switches. The device is fully specified for a 3.0V application.
A headphone or mute detection is included in the AS1748 and AS1750. This function is realized with a comparator
which has an internally generated thresh-hold of about 1/3 of V CC. To reduce click-and-pop sounds when switching
between precharged points the AS1749 an d AS1750 have an internal shunt switch. This shunt switch automatically
discharges any capacitance at the NO and NC connection points.
9 Application Information
Digital Control Inputs
The logic inputs of the AS1747– AS1750 accept up to +5.5V independent of the supply voltage. Due to this a mixing of
the logic levels in a system is possible. For example, with a +3.3V supply, IN_ can be driven low to GND and high to
+5.5V. For a +1.8V supply voltage, the logic levels are 0.5V (low) and 1.4V (high); for a +5V supply voltage, the logic
levels are 0.8V (low) and 2.0V (high).
Analog Signal Levels
The change of the on-resistance of the AS1747– AS1750 is very little for analog input signals over the whole supply
voltage range. The switches are bi-directional, so the NO_, NC_, and COM_ pins can be either inputs or outputs.
The AS1747– AS1750 pass signals as low as VCC - 5.5V, includi ng signals below ground with minimal distortion.
Comparator (AS17481/AS1750)
To implement a mute and headphone function, a comparator is included in the AS1748 and AS1750. The negative ter-
minal of this comparator is connected to the outside (via pin CMP-) while the positive terminal is internally set to VCC/3.
The output of the comparator (CMPO) is logic high when the negative terminal (CMP-) is below the threshold. CMPO is
logic low when CMP- is higher than V CC/3.
Headphone audio signals are typical biased to VCC/2 so a comparator threshold of VCC/3 is sufficient for the head-
phone detection.
Shunt Switch (AS17491/AS1750)
Due to the switching between audio sources, audible click-and-pop sounds occur . To reduce this sounds a 100Ω shunt
switch is implemented in the AS1749 and AS1750. This shunt switch automatically discharges any capacitance at the
NC_ or NO_ terminals when th ey ar e unconnected to COM_.
Audible clicks and pops are caused when a step DC voltage is switched into the speaker . By automatically discharging
the side that is not connected, any residual DC voltage is removed, thereby reducing the clicks and pops.
Power-Supply Sequencing and Overvoltage Protection
Caution: Stresses beyond the listed absolute maximum ratings in Table 3 on page 4 may cause permanent damage
to the device. Exposure to absolute maximum rating conditions for extended periods may affect device
reliability.
Proper power-supply sequencing is recommended for all CMOS devices. Always apply VCC before applying analog
signals, especially if the analog signal is not current-limited.
