External Components Description (Refer to the Application/Test Circuit)
Components Description
RI
Inverting input resistance to provide AC gain in conjunction with RF. This input is
biased at the BIASCAP voltage (approximately 2.5VDC).
RF
Feedback resistor to set AC gain in conjunction with RI. Please refer to the Amplifier
Gain paragraph, in the Application Information section.
CI
AC input coupling capacitor which, in conjunction with RI, forms a high-pass filter at

RFBA
Feedback divider resistor connected to V5. This value of this resistor depends on
the supply voltage setting and helps set the TDA2075A gain in conjunction with RI,
RF, RFBA, and RFBC. Please see the Modulator Feedback Design paragraphs in the
Application Information Section.
RFBB
Feedback divider resistor connected to AGND. This value of this resistor depends
on the supply voltage setting and helps set the TDA2075A gain in conjunction with
RI, RF, RFBA, and RFBC. Please see the Modulator Feedback Design paragraphs in
the Application Information Section.
RFBC
Feedback resistor connected from either the OUT1 (OUT2) to FBKOUT1
(FBKOUT2) or PGND1 (PGND2) to FBKGND1 (FBKGND2). The value of this
resistor depends on the supply voltage setting and helps set the TDA2075A gain in
conjunction with RI, RF, RFBA,, and RFBB. It should be noted that RFBC must have a
power rating of greater than

. Please see the Modulator
Feedback Design paragraphs in the Application Information Section.
CFB
Feedback delay capacitor that both lowers the idle switching frequency and filters
very high frequency noise from the feedback signal, which improves amplifier
performance. The value of CFB should be different for channel 1 and channel 2 to
minimize noise coupling between the channels. Please refer to the Application /
Test Circuit.
ROFA
Potentiometer used to manually trim the DC offset on the output of the TDA2075A.
ROFB
Resistor that limits the DC offset trim range and allows for precise adjustment.
COF
Capacitor that filters the manual DC offset trim voltage.
RREF
Bias resistor. Locate close to pin 34 and ground to plane with a low impedance
connection to pins 41 and 42.
RBBMSET
Bias current setting resistor for the BBM setting. Locate close to pin 7 and ground
directly to pin 5. See Application Information on how to determine the value for
RBBM.
CA
BIASCAP decoupling capacitor. Locate close to pin 3 and ground to plane with a
low impedance connection to pins 41 and 42.
CS
Supply decoupling capacitor for the power pins. For optimum performance, these
components should be located close to the TDA2075A and returned to their
respective ground as shown in the Application Circuit.
RVNN1
Main overvoltage and undervoltage sense resistor for the negative supply (VNN).
Please refer to the Electrical Characteristics Section for the trip points as well as the
hysteresis band. Also, please refer to the Over / Under-voltage Protection section in
the Application Information for a detailed discussion of the internal circuit operation
and external component selection. When using a single power supply, this circuit
can be defeated by connecting a 16K
Ω resistor to AGND.
RVNN2
Secondary overvoltage and undervoltage sense resistor for the negative supply
(VNN). This resistor accounts for the internal VNNSENSE bias of 1.25V. Nominal
resistor value should be three times that of RVNN1. Please refer to the Over / Under-
voltage Protection section in the Application Information for a detailed discussion of
the internal circuit operation and external component selection. When using a single
power supply, omit RVNN2.
RVPP1
Main overvoltage and undervoltage sense resistor for the positive supply (VPP).
Please refer to the Electrical Characteristics Section for the trip points as well as the
hysteresis band. Also, please refer to the Over / Under-voltage Protection section in
the Application Information for a detailed discussion of the internal circuit operation
and external component selection.
RVPP2
Secondary overvoltage and undervoltage sense resistor for the positive supply
