NOTE
1.
The closed gain should be 6dB or higher to prevent the oscillation. Unity gain follower application may cause the
oscillation.
2.
Minimize the load capacitor for the better performance. A large load capacitor CL reduces the frequency response and
causes oscillation or ringing.
3. Be careful to the circuit of high impedance. Input bias current influences an input noise and output offset voltage.

POWER DISSIPATION vs. AMBIENT TEMPERATURE
IC is heated by own operation and possibly gets damage when the junction power exceeds the acceptable value called Power
Dissipation P
D
. The dependence of the MUSES8832 P
D
on ambient temperature is shown in Fig 1. The plots are depended on
following two points. The first is P
D
on ambient temperature 25ºC, which is the maximum power dissipation. The second is 0W,
which means that the IC cannot radiate any more. Conforming the maximum junction temperature Tjmax to the storage
temperature Tstg derives this point. Fig.1 is drawn by connecting those points and conforming the P
D
lower than 25ºC to it on
25ºC. The P
D
is shown following formula as a function of the ambient temperature between those points.
Dissipation Power
P
D
=
Tjmax - Ta
ja
[W] (Ta=25ºC to Ta=150ºC)
Where,
ja
is heat thermal resistance which depends on parameters such as package material, frame material and so on.
Therefore, P
D
is different in each package.
While, the actual measurement of dissipation power on MUSES8832 is obtained using following equation.
(Actual Dissipation Power) = (Supply Current Icc) X (Supply Voltage V
+
– V-) – (Output Power Po)
The MUSES8832 should be operated in lower than P
D
of the actual dissipation power.
To sustain the steady state operation, take account of the Dissipation Power and thermal design.
