Application information
4.1
Differential configuration principle
The TS2007 is a monolithic fully-differential input/output class D power amplifier. The
TS2007 includes a common-mode feedback loop that controls the output bias value to
average it at VCC/2 in the range of DC common mode input voltage. This allows the device
to always have a maximum output voltage swing, and by consequence, maximize the output
power. In addition, as the load is connected differentially compared to a single-ended
topology, the output is four times higher for the same power supply voltage.
A fully-differential amplifier has the following advantages.
●
High PSRR (power supply rejection ratio).
●
High CMRR (common mode noise rejection).
●
Virtually zero pop without additional circuitry, giving a faster start-up time than
conventional single-ended input amplifiers.
●
Easy interfacing with differential output audio DACs.
●
No input coupling capacitors required since there is a common mode feedback loop.
4.2
Gain settings
In the flat region of the frequency-response curve (no input coupling capacitor or internal
feedback loop + load effect), the differential gain can be set to either 6 or 12 dB depending
on the logic level of the GS pin.
Note:
Between the GS pin and VCC there is an internal 300 kΩ resistor. When the pin is floating
the gain is 6 dB. In standby mode, this internal resistor is disconnected (HiZ input).
4.3
Common mode feedback loop limitations
As explained previously, the common mode feedback loop allows the output DC bias voltage
to be averaged at VCC/2 for any DC common mode bias input voltage.
mode feedback loop can fulfill its role only within the defined range.
4.4
Low frequency response
If a low frequency bandwidth limitation is required, it is possible to use input coupling
capacitors. In the low frequency region, the input coupling capacitor Cin has a greater effect.
Cin and the input impedance Zin form a first-order high-pass filter with a -3 dB cut-off
