Applications
The 3PEAK INCORPORATED TPF603/605/607 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-kload with single 5V
supply voltage. The TPF603 has differential inputs,
the TPF605/607 support single-ended inputs, and
all can use external resistors for flexible gain setting.
The TPF603/605/607 has built-in enable/shutdown
control for pop-free on/off control. The TPF603/605
have an external under-voltage detector that mutes
the output when monitored voltage drop below set
value. Using the TPF603/605/607 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.

AC-Coupling Input Capacitors
        
TPF603 / TPF605 / TPF607
3-VRMS Audio Line Driver with Integrated Charge Pump
Because of the integrated charge pump that generates negative rail, TP603/605/607 may be used to amplify audio
signal so the output DC voltage is 0V. This usually requires the DC voltage of the input signal to be 0V. If the input
signal has a DC level other than 0V, an AC-coupling capacitor is necessary to block the DC voltage.
The AC-coupling capacitor essentially forms a high-pass filter at the input. The cut-off frequency of the filter has to be
low enough not to distort the input audio signal. For an inverting amplifier shown in Figure 4 the cut-off frequency may
be calculated
           
as
   
following:

If the required maximum cut-off frequency is known, the minimum AC-coupling capacitance can be determined:

2RINfc
Adding Low-Pass Filtering to the Gain
(2)
If low-pass filtering is necessary in addition to the audio signal amplification, a second-order filter can be implemented
as shown in Figure 5. Choice of C3, R1, R2, and R3 is based on the gain setting requirement and AC-coupling cut-off
frequency as discussed above. C1, C2 and C4 may be calculated depending on the bandwidth. Example choices of R
and C are listed in Table 1. If first-order filtering satisfies performance requirements, simply remove the C2 and C4 to
lower the component counts.

Pop-Free Power Up and Power Down
During power up or power down, the input device that provide audio source may experience significant DC level shift.
Charging of the input capacitor due to DC shift will cause pop noise. It is recommended that TPF603/605/607 is
disabled (EN low) during power up and power down and kept disabled until charging of the input capacitor is complete.
The sequence of EN control is illustrated below.
