(2) Although we are confident in recommending the sample application circuits, carefully check their characteristics further when using them. When modifying externally attached component constants before use, determine them so that they have sufficient margins by taking into account variations in externally attached components and the Rohm LSI, not only for static characteristics but also including transient characteristics. (3) Absolute maximum ratings If applied voltage, operating temperature range, or other absolute maximum ratings are exceeded, the LSI may be damaged. Do not apply voltages or temperatures that exceed the absolute maximum ratings. If you think of a case in which absolute maximum ratings are exceeded, enforce fuses or other physical safety measures and investigate how not to apply the conditions under which absolute maximum ratings are exceeded to the LSI. (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 allowable power dissipation in actual states of use. (6) Shorts between pins and misinstallation When mounting the LSI on a board, pay adequate attention to orientation and placement discrepancies of the LSI. If it is misinstalled and the power is turned on, the LSI may be damaged. It also may be damaged if it is shorted by a foreign substance coming between pins of the LSI or between a pin and a power supply or a pin and a GND. (7) Operation in strong magnetic fields Adequately evaluate use in a strong magnetic field, since there is a possibility of malfunction. (8) About Operating Voltage Range and Operating Temperature Range The circuit functional operations are guaranteed within the Operating Voltage Range and Operating Temperature Range. The standard values of electrical characteristics, however, are guaranteed under the specific conditions. Accordingly, careful consideration of the IC characteristic variations is required to design a set of circuit. (9) About power ON/OFF (a) At power ON/OFF, a shock sound will be generated and, therefore, use MUTE on the set. (b) When turning on power supplies, VEE and VCC should be powered on simultaneously or VEE first; then followed by VCC. If the VCC side is started up first, an excessive current may pass VCC through VEE. (10) About serial control For the CL and DA terminals, the patterned and other wirings should be routed not to cause interference with the analog-signal-related lines. (11) About function switching When switching Input Selector or Input Gain, use MUTE on Master Volume. www.rohm.com © 2010 ROHM Co., Ltd.
