TDA3501 VIDEO CONTROL COMBINATION:


The TDA3501 is a monolithic integrated circuit performing the control functions in a PAL/SECAM
decoder which additionally comprises the integrated circuits TDA3510 (PAL decoder) and/or
TDA3520 (SECAM decoder).
The required input signals are: luminance and colour difference —(R-Y) and —(B-Y),
while linear RGB signals can be inserted from an external source.
RGB signals are provided at the output to drive the video output stages.
The TDA3501 has the following features:
- capacitive coupling of the input signals
- linear saturation control
- (G-Y) and RGB matrix insertion possibility of linear RGB signals, e.g. video text, video games, picture-in-picture, camera or slidescanner
- equal black level for inserted and matrixed signals by clamping
- 3 identical channels for the RGB signals
- linear contrast and brightness control, operating on both the inserted and matrixed RGB signals
- horizontal and vertical blanking (black and ultra-black respectively) and black-level clamping
obtained via a 3-level sandcastle pulse
- differential amplifiers with feedback-inputs for stabilization of the RGB output stages
- 2 d.c. gain controls for the green and blue output signals (white point adjustment)
- beam current limiting possibility

TDA2030 DESCRIPTION
The TDA2030 is a monolithic integrated circuit in
Pentawatt package, intended for use as a low
frequency class AB amplifier. Typically it provides
14W output power (d = 0.5%) at 14V/4Ω;at ± 14V
the guaranteedoutput poweris 12W on a 4Ω load
and 8Won a 8Ω (DIN45500).
TheTDA2030provideshighoutputcurrentandhas
very lowharmonic and cross-over distortion.
Further the device incorporates an original (and
patented) short circuit protection system compris-
ing an arrangement for automatically limiting the
dissipated power so as to keep the working point
of the outputtransistorswithin their safe operating
area.A conventionalthermal shut-downsystem is
also included.


SHORT CIRCUIT PROTECTION
The TDA2030 has an original circuit which limitsthe
current of the output transistors , the maximum output current is a function of the
collector emitter voltage; hence the output transis-
tors work within their safe operating area .
This functioncan thereforebe consideredas being
peak power limiting rather than simple current lim-
iting.
It reducesthe possibility that the devicegetsdam-
aged during an accidental short circuit from AC
output to ground.

Tone Control IC TDA4290

TDA4290-2
Bipolar IC


Tone control IC for the DC voltage control of volume, treble, and bass. The volume characteristic
can be changed from linear to physiological.

For mono application we recommend the TDA 4290-2, while the TDA 4290-2 S is especially
suitable for stereo application.
