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

Transcription

1 9-352; Rev 2; /6 Low-Voltage, Dual SPDT, Audio Clickless General Description The 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 +.8V to +5.5V supply and have low.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 -4 C to +85 C extended temperature range.

8 AUDIO SOURCE OUT+ NC NO NC2 MAX4765 SHUNT SWITCH Figure. Typical Operating Circuit COM MUTE BUTTON Detailed Description The are low on-resistance, low-voltage, dual SPDT analog switches that operate from a +.8V to +5.5V supply and are fully specified for nominal 3.V 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 /3 of. 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 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 +.8V supply voltage, the logic thresholds are.5v (low) and.4v (high); for a +5V supply voltage, the logic thresholds are.8v (low) and 2.V (high). IN IN2 COM2 OUT- OUT+ AUDIO SOURCE 2 MUTE OUT- NO2 V+ 3 CMPO CMP- V+ INPUT SELECT 8Ω SPEAKER 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 pass signals as low as - 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 / 3. When the negative terminal (CMP-) is below the threshold, the comparator output (CMPO) is a logic high. When CMP- rises above / 3, CMPO is a logic low. The comparator threshold of / 3 allows for detection of headphones because headphone audio signals are typically biased to / 2. Shunt Switch (MAX4764/MAX4764A/MAX4765) The Ω 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 before applying analog signals, especially if the analog signal is not current-limited.
