MAXIM MAX4762, MAX4764, MAX4764A, MAX4765 Technical data

General Description

The MAX4762–MAX4764/MAX4764A/MAX4765 dual SPDT (single-pole/double-throw) 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 0.6Ω 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/MAX4764A/MAX4765 have an internal shunt switch to automatically discharge any capacitance at the NO and NC connection points. This reduces click-and-pop sounds that occur when switching audio signals between precharged points.

These SPDT switches are available in space-saving µMAX®, TDFN, thin QFN, and UCSP™packages and operate over the -40°C to +85°C extended temperature range.

MAX4762–MAX4764/MAX4764A/MAX4765

Detailed Description

The MAX4762–MAX4764/MAX4764A/MAX4765 are low on-resistance, low-voltage, 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-before-make 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/MAX4764A/MAX4765 feature an internal shunt switch to discharge any capacitance at the NO and NC connection points. This reduces the clickand-pop sounds that occur when switching audio signals.

Applications Information

Digital Control Inputs

The MAX4762–MAX4764/MAX4764A/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 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).

Analog Signal Levels

The on-resistance of the MAX4762–MAX4764/ MAX4764A/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–MAX4764/MAX4764A/MAX4765 pass signals as low as VCC- 5.5V, including signals below ground with minimal distortion.

Comparator (MAX4763/MAX4765)

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 V

CC

/ 3. When the negative terminal (CMP-) is below the threshold, the comparator output (CMPO) is a logic high. When CMP- rises above V

CC

/ 3, CMPO is a logic low.

The comparator threshold of V

CC

/ 3 allows for detection of headphones because headphone audio signals are typically biased to V

CC

/ 2.

Shunt Switch

(MAX4764/MAX4764A/MAX4765)

The 100Ω shunt switches on the MAX4764/MAX4764A/ 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.

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 VCCbefore applying analog signals, especially if the analog signal is not current-limited.

MEASUREMENTS ARE STANDARDIZED AGAINST SHORTS AT IC TERMINALS. OFF-ISOLATION IS MEASURED BETWEEN COM_ AND "OFF" NO_ OR NC_ TERMINAL ON EACH SWITCH. ON-LOSS IS MEASURED BETWEEN COM_ AND "ON" NO_ OR NC_ TERMINAL ON EACH SWITCH. CROSSTALK IS MEASURED FROM ONE CHANNEL TO THE OTHER CHANNEL. SIGNAL DIRECTION THROUGH SWITCH IS REVERSED; WORST VALUES ARE RECORDED.
