Low-Voltage, Dual SPDT, Audio Clickless Switches with Negative Rail Capability
General Description
The MAX4762-MAX4765 dual SPDT (single-pole/doublethrow) switches feature negative signal capability that allows signals below ground to pass through without distortion. These analog switches operate from a single +1.8V to +5.5V supply and have low 0.6 on-resistance, making them ideal for switching audio signals. The MAX4763/MAX4765 include a comparator that can be used for headphone detection or a mute/send key function. The MAX4764/MAX4765 have an internal shunt switch to automatically discharge any capacitance at the NO and NC connection points. This reduces click-andpop sounds that occur when switching audio signals between precharged points. These SPDT switches are available in space-saving MAX, TDFN, thin QFN, and UCSPTM packages and operate over the -40C to +85C extended temperature range.

The on-resistance of the MAX4762-MAX4765 changes very little for analog input signals across the entire supply voltage range (see the Typical Operating Characteristics). The switches are bidirectional, so the NO_, NC_, and COM_ pins can be either inputs or outputs. The MAX4762-MAX4765 pass signals as low as VCC 5.5V, including signals below ground with minimal distortion.
Comparator (MAX4763/MAX4765)
NC2 OUT+ AUDIO SOURCE 2 MUTE CMPO CMPMUTE BUTTON OUTNO2 V+ 3 IN2 COM2 V+
The MAX4763/MAX4765 include a comparator that can be used for mute and headphone detection functions. The positive terminal of the comparator is internally set to VCC / 3. When the negative terminal (CMP-) is below the threshold, the comparator output (CMPO) is a logic high. When CMP- rises above VCC / 3, CMPO is a logic low. The comparator threshold of VCC / 3 allows for detection of headphones because headphone audio signals are typically biased to VCC / 2.
Shunt Switch (MAX4764/MAX4765)
The 100 shunt switches on the MAX4764/MAX4765 automatically discharge any capacitance at the NC_ or NO_ terminals when they are unconnected to COM_. This reduces audible click-and-pop sounds that occur when switching between audio sources. 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.
Figure 1. Typical Operating Circuit
Detailed Description
The MAX4762-MAX4765 are low on-resistance, lowvoltage, dual SPDT analog switches that operate from a +1.8V to +5.5V supply and are fully specified for nominal 3.0V applications. The devices feature a negative signal capability that allows signals below ground to pass through without distortion and have break-beforemake switching. The MAX4763/MAX4765 feature a comparator that can be used for headphone or mute detection. The comparator threshold is internally generated to be approximately 1/3 of VCC. The MAX4764/MAX4765 feature an internal shunt switch to discharge any capacitance at the NO and NC connection points. This reduces the click-and-pop sounds that occur when switching audio signals.
Power-Supply Sequencing and Overvoltage Protection
Caution: Do not exceed the absolute maximum ratings since stresses beyond the listed ratings may cause permanent damage to the device. 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.
Applications Information
Digital Control Inputs
The MAX4762-MAX4765 logic inputs accept up to +5.5V, regardless of supply voltage. For example, with a +3.3V supply, IN_ can be driven low to GND and high to +5.5V allowing for mixing of logic levels in a system. Driving IN_ Rail-to-Rail(R) minimizes power consumption. For a +1.8V supply voltage, the logic thresholds are 0.5V (low) and 1.4V (high); for a +5V supply voltage, the logic thresholds are 0.8V (low) and 2.0V (high).
