The 3PEAK INCORPORATED TPF632 are 2-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
2-VRMS into a 2.5-kΩ load with single 3.3V supply
voltage. The device has differential inputs, and can
use external resistors for flexible gain setting.
The TPF632 has built-in enable/shutdown control
for pop-free on/off control. The device has an
external under-voltage detector that mutes the
output when monitored voltage drop below set value.
Using the TPF632 in audio products can reduce
component count considerably compared to
traditional methods of generating a 2-VRMS output.
The device needs only a single 3.3V supply to
generate 5.6-VPP output while a 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.
