technical note 15/17 www.rohm.com 2010.06 - rev.a ? 2010 rohm co., ltd. all rights reserved. bd3811k1,BD3818KS 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 circui ts may cause variations in both static and trans ient characteristics for external compo nents 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 r egarding 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 ev en when operating below it. act ually confirm that the voltage of each pin does not become a lower voltage t han 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 m ounting direction or shorts betw een 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. 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. 9. power on/off (a) at power on/off, a shock sound will be g enerated. 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. function switching 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. ground line the ground pin: 47pin (BD3818KS) should be connected to the ground line with as low noise as the agnd pin. 12. switching noise reduction at switching vo lume from -3db to -4db (bd3811k1 only) in order to reduce a switching noise at the switching volume from -3db to -4db, the -4db-s tep switch should be switched first, and then the -1db-step switch by -1db. downloaded from: http:///
