ordering number : enn6867 20901rm (ot) no. 6867-1/28 overview the LC75343m is an electronic volume system that can control the volume, balance, 2-band equalizer, super bass, and input switching functions by serial data input. functions volume: 0 db to ?8 db (1-db step) and (64 positions) 0 db to ?0 db (1-db step), ?0 db to ?0 db (2-db step), ?0-db to ?8 db (4-db step) balance function with separate l/r control treble: ?0-db control in 2-db steps is possible. shelving characteristic. bass*: ?0-db control in 2-db steps is possible. peaking characteristics. super bass*: +10-db control in 2-db steps is possible. peaking characteristics. (+/?0 db control in 2-db steps is possible depending on software support and the application. peaking characteristics.) selector: 5 input signals can be selected both for l and r input gain: 0 db to +30 db (2-db step) amplification is possible for the input signal. general-purpose amp (att): 2 on-chip general-purpose amplifiers (0-db to ?8-db in 2-db steps and 11 positions attenuate control is possible, depending on software support and the application) note*: regarding (bass) and (super bass) above, mid and bass functions can also be realized by changing the capacitor capacitance. features on-chip buffer amplifier cuts down number of external components low switching noise generated by on-chip switch due to use of silicon gate cmos process on-chip reference voltage circuit for analog ground controls performed with serial data input (ccb) package dimensions unit: mm 3263-mfp36sdj (375 mil) 1 18 36 19 0.8 15.2 0.3 0.65 10.5 7.9 0.25 (0.8) 2.45max 0.1 (2.25) sanyo: mfp36sdj (375 mil) [LC75343m] LC75343m sanyo electric co.,ltd. semiconductor company tokyo office tokyo bldg., 1-10, 1 chome, ueno, taito-ku, tokyo, 110-8534 japan electronic volume control system on-chip cmos ic any and all sanyo products described or contained herein do not have specifications that can handle applications that require extremely high levels of reliability, such as life-support systems, aircraft? control systems, or other applications whose failure can be reasonably expected to result in serious physical and/or material damage. consult with your sanyo representative nearest you before using any sanyo products described or contained herein in such applications. sanyo assumes no responsibility for equipment failures that result from using products at values that exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges, or other parameters) listed in products specifications of any and all sanyo products described or contained herein. ccb is a trademark of sanyo electric co., ltd. ccb is sanyo? original bus format and all the bus addresses are controlled by sanyo.
