M52732SP
3-CHANNEL VIDEO AMPLIFICA TION
DESCRIPTION
The M52732SP is a semiconductor integrated circuit that has 3channels of built-in amplifiers in the broad-band video amplifier
having a 75MHz band. Every channel is provided with a broad-band
amplifier, contrast control (main and sub), and brightness control. It
accordingly has an optimal configuration for use with high
resolution color display monitors.
FEATURES
It realize low power dissipation so that 3-channels are built in.

ELECTRICAL CHARACTERISTICS TEST METHOD
1. About switch numbers (SW Nos.) since those f or the signal and
pulse input pins are listed in Attached Table 1, the following
notes omit them. Only SW Nos. for the e xternal power supply will
be indicated in the Notes.
2. since sub contrast voltges V3, V7, and V11, they are also set to
the same value, so that V3 in attached Table 1 represents all.
CC Circuit current

Conditions shall be as indicated in Attached Table 1. Measure
these conditions using ampere meter A with SW1 set to a.
Vomax Output dynamic range
1. Follow the procedure below to set V15.
Input SG1 to pin 10 (pin 6, 2) and raise V15 slowly. Read the
voltage of V15 when the higher peak of output w av eform of T.P20
(T.P24, 28) begins distortion. This voltage is V
Next, reduce V15 slo wly. Read the v oltage of V15 when the low er
peak of output waveform of T.P20 (T.P24, 28) begins distortion.
This voltage is VTR2 (VTG2, VTB2).

1. Under conditions in attached Table.
2. Input SG1 to pin 10 (pin 6, 2). Read amplitude of the output at
T.P20 (T.P24, 28), which is VOR1 (VOG1, VOB1).
3. The maximum gain G is:

1. Conditions are identical with those in Attached Table except
setting V13 to 6.0V.
2. Then read amplitude of the output at T.P20 (T.P24, 28), which is
VOR2 (VOG2, V OB2)

Change the procedure according to output pins.
Use V
TR1 when measuring T.P20. Similarly, VTG1 for T .P24, VTB1
for T.P28.
2. Set V15 to VTR (VTG, VTB), then slowly raise SG1 amplitude
starting from 700mV. Measure the output amplitude when the
higher and lower peaks of T.P20 (T.P24, T.P28) output waveform
simultaneously begin distortion.
Vimax Maximum input
Under the conditions in Note 2, vary V13 to 6.7V as indicated in
Attached Table 1, then slowly raise amplitude of the input signal
starting from 700mV
P-P. Read the amplitude of the input signal
when the output signal begins distortion.
