Description
The 3PEAK TPF632C/605C/607C are 3-VRMS pop-
free stereo line drivers with the integrated charge
pump generating the negative supply rail which
allows the removal of the output DC-blocking
capacitors. The devices are capable of driving 3-
VRMS into a 2.5-kΩ load with single 5V supply voltage.
The TPF632C has differential inputs, the
TPF605C/607C support single-ended inputs, and all
can use external resistors for flexible gain setting.
The 3PEAK TPF632C/605C/607C has built-in
enable/shutdown control for pop-free on/off control.
The TPF632C/605C has an external under-voltage
detector that mutes the output when monitored
voltage drop below set value. Using the
TPF632C/605C/607C in audio products can reduce
component count considerably compared to
traditional methods of generating a 3-VRMS output.
The device needs only a single 5V supply to
generate 8.5-VPP output while traditional op-amp
requires a split-rail power supply to achieve same.
The device is ideal for single-supply electronics
where size and cost are critical design parameters.

Note 1: Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. Exposure to any Absolute Maximum Rating
condition for extended periods may affect device reliability and lifetime.
Note 2: The inputs are protected by ESD protection diodes to each power supply. If the input extends more than 500mV beyond the power supply, the input
current should be limited to less than 10mA.
Note 3: A heat sink may be required to keep the junction temperature below the absolute maximum. This depends on the power supply voltage and how many
amplifiers are shorted. Thermal resistance varies with the amount of PC board metal connected to the package. The specified values are for short traces
connected to the leads.
