This IC's package is POWER-SSOP, so
improving the board on which the IC is
mounted enables a large power dissipation
without a heat sink.
For example, using an 1 layer glass epoxy
resin board, the IC's power dissipation is
2.6W at least. And it comes to 3.6W by
using an improved 2 layer board.
The information of the N, P, O type board is
shown in attached.

The input resisters, the 10kΩ resister to the non-inverted input and,
the 2kΩ resister to the inverted input, are built-in the operational amplifier.
Therefore the composition value of the external input resisters(R1 R2)

The notes on designing the layout of the board
This IC has direct PWM controls for the Spindle channel and the
Slide channel drive, therefore the circuits of the IC are influenced
more easily by the PWM switching noise than those have linear
controls. Please refer to the following notes on the ocasion of
designing the layout pattern of the board on which the IC is
mounted.
The bad influence of the PWM noise differs in each board,
therefore please consider the following notes as the reference
materials for designing the board.
Note 1
It is necessary for some application in order to reduce the PWM
noise that pass condensers are connected between power supply
pins(VM23:4pin, VM1:22pin, VM4:38 pin, 5VCC:39pin) and GND
pin, even if the power supplies of the application already have pass
condensers. The closer the connection points of the condensers
are to the pins, the more effective it is to reduce the noise.
Please refer to the values of the condensers on the page of [An
example of the values of the external parts.
(The value of the condensors is only a reference value. It differs in
each application because the bad influence of PWM noise relates
to the layout pattern of the board.)
Note 2
The feedback point of the Spindle channel [the Slide channel] is
the connected point to the VM1(22pin) [the VM23(4pin)] line from
the RSP(15pin) [RSL(8pin)] pin through the sensing resistor
RSP[RSL]. Therefore the closer the feedback point is to the power
supply pin, the more stable the circuits are for the PWM noise.
cf. [application circuit]
Note 3
The farther the large current output lines(especially PWM output
lines of the Spindle CH. and the Slide CH.) which are indicated as
wide lines in the Fig. [application circuit] are to the small signal
input lines, the less the bad influence of the PWM noise comes to
be without the cross-talk between a large current output line and a
small input signal line.
Note 4
In case the PWM switching noise influences the REF input, it is
necessary for some application that a condenser is connected
between REF pin(25pin) and GND pin. The closer the connection
points of the condensers are to the pins, the more effective it is to
reduce the noise. (This is the same as note1.)
cf.[application circuit], [An example of the values of the external
parts]
Note 5
The closer the GND side of the capacitor connected with OSC pin
(30 pin) is to the GND pin(33pin), which is the nearest GND to the
GND of the small signal circuit inside the IC, the less the bad
influence of the PWM noise on the GND line comes to be.
