DESCRIPTION
Realized with a high voltage bipolar technology,the
TDA8153 is a monolithic RGB video output stage
for TV color applications. It drives the CRT cath-
odes directly and offers a video bandwidth compat-
ible with CCIR standards . In addition to three
independent video amplifiers, the device features
an internal generator for the first grid voltage,
flashover protection, cathode short circuit protec-
tion and a common cut-off sensing output for use
in sequential sampling applications.
The TDA8153 is supplied in a 15 lead Multiwatt
plastic power package.

6
RED INPUT
Input of 'Red' Video Amplifier. See pin 7.
7
GREEN INPUT
Input of "Green" Video Amplifier. The bias voltage at the inputs is equal to V
ref

BE
. Other
inputs are pin 6 (red) and pin 9 (blue).
8
GROUND
Ground Connection (pin 8 is also connected to the tab).

BLUE INPUT
Input of 'Blue' Video Amplifier. See pin 7.
10
V
ref
The reference voltage for the three amplifiers is available on this pin. Typical value is 1.6V. The
capacitor connected between pin 10 and ground eliminates AC crosstalk between the amplifiers.
11
V
s
Supply Voltage Input for Low Voltage Circuitry, typically 12V.
12
SAMPLING
Cathode Current Sampling Output. Provides sum of cathode currents for automatic cut-off
adjustment with video processors using the sequential system. The three current generators I

bias the inputs of this circuit which performs the cut-off adjustment, allowing also
adjustment with in flowing CRT leakages.
13
BLUE OUTPUT
Output of 'Blue' Video Amplifier. See pin 15.
14 BLUE FEEDBACK Feedback Output for 'Blue' Amplifier. See pin 1.
15
GREEN OUTPUT
Output of the 'Green' Video Amplifier. The output is protected against CRT flashovers. Other
outputs are pin 3 (red) and pin 13 (blue).
