Notes for use
1. Numbers and data in entries are representative design values and are not guaranteed values of the items.
2. Although ROHM is confident that the example application circuit reflects the best possible recommendations, be sure to
verify circuit characteristics for your particular application. Modification of constants for other externally connected circuits
may cause variations in both static and transient characteristics for external components as well as this Rohm IC. Allow for
sufficient margins when determining circuit constants.
3. Absolute maximum ratings
Use of the IC in excess of absolute maximum ratings, such as the applied voltage or operating temperature range (Topr),
may result in IC damage. Assumptions should not be made regarding the state of the IC (short mode or open mode) when
such damage is suffered. A physical safety measure, such as a fuse, should be implemented when using the IC at times
where the absolute maximum ratings may be exceeded.
4. VEE potential
Make the VEE pin voltage such that it is the lowest voltage even when operating below it. Actually confirm that the
voltage of each pin does not become a lower voltage than the VEE pin, including transient phenomena.
5. Thermal design
Perform thermal design, in which there are adequate margins, by taking into account the power dissipation (Pd) in actual
states of use.
6. Short circuit between terminals and erroneous mounting
Pay attention to the assembly direction of the ICs. Wrong mounting direction or shorts between terminals, GND, or other
components on the circuits, can damage the IC.
7. Operation in strong electromagnetic field
Using the ICs in a strong electromagnetic field can cause operation malfunction.
8. Operating Voltage Range and Operating Temperature Range
Circuit function actions are guaranteed within the action voltage range and the action temperature range. However, the
specific values of the electrical characteristics are guaranteed under the specified conditions of the electrical
characteristics. Therefore, carry out set considerations in sufficient consideration of IC characteristic fluctuations..
9. Power ON/OFF
(a) At power ON/OFF, a shock sound will be generated. Therefore, use MUTE on the set.
(b) When turning on power supplies, VEE and VCC should be powered on simultaneously, or VEE first followed by
VCC. If the VCC side is started up first, an excessive current may flow from VCC to VEE.
10. Serial control
For the CL and DA terminals, the patterned and other wirings should be routed as not to cause interference with the
analog-signal-related lines.
11. Function switching
For all functions, other than Master Volume, Treble, and Bass Gain Settings, use MUTE on the set.
