Outline FEATURES Selection of delay time in a range between 0.5msec and 32.0msec in 64 increments of 0.5msec Selection of delay time is controlled by serial data Built-in A-D, D-A converters,input/output low-pass filter, and 16K bit memory High sound quality is assured by simple system construction,due to A-D, D-A converters with ADM (Adaptive Delta Modulation) system Output noise voltage : -95dBV (typ) Total harmonic distortion : 0.2% (typ) Outline 24P4 (BP) 2.54mm pitch 600mil DIP (13.0mm X 31.1mm X 3.8mm) RECOMMENDED OPERATING CONDITIONS Supply voltage range Rated supply voltage VCC,VDD=4.5 to 5.5V VCC,VDD=5V Outline 24P2W-A(BFP) 1.27mm pitch 450mil SOP (8.4mm X15.0mm X2.0mm) SYSTEM CONFIGURATION BUFFER Lch In M65830BP / FP *1 MODE SWITCH ∑ Lch Out ∆ ∑ + DIGITAL DELAY -1 -1 SLch Out SRch Out BUFFER Rch In EFFECT VOLUME *2 EFFECT SWITCH ∑ Notes *1 Mode switch : ∆ L-R Stereo input Mode switch : ∑ L+R Monaural input *2 Effect switch ON: Surround output disabled ( 2 loudspeakers ) OFF:Surround output enabled( 4 loudspeakers ) Rch...
