The 3PEAK TPF632A/605A/607A are 3-VRMSpop-free stereo line drivers with the integratedcharge pump generating the negative supply railwhich allows the removal of the output DC-blockingcapacitors. The devices are capable of driving3-VRMS into a 2.5-kΩ load with single 5V supplyvoltage. The TPF632A has differential inputs, theTPF605A/607A support single-ended inputs, and allcan use external resistors for flexible gain setting.The 3PEAK TPF632A/605A/607A has built-inenable/shutdown control for pop-free on/off control.The TPF632A/605A has an external under-voltagedetector that mutes the output when monitoredvoltage drop below set value. Using theTPF632A/605A/607A in audio products can reducecomponent count considerably compared totraditional methods of generating a 3-VRMS output.The device needs only a single 5V supply togenerate 8.5-VPP output while traditional op-amprequires a split-rail power supply to achieve same.The device is ideal for single-supply electronicswhere size and cost are critical design parameters.
