APPLICATIONS
This chapter gives examples of applications where the DL716
is suitable.
MD Player
MD (Mini Disk) players incorporate various mechanical and
electrical components, and thus there are a wide variety of signals
to be measured, such as servomechanism, sound, and digital data
signals (see Figure 9). With the DL716, different servo signals or
sound signals that require isolated measurement (more than 10
isolated analog channels), can be measured together with digital
signals surrounding the micro computer (approximately 40 bits).
MD players are characterized by high-speed pre-read control
to avoid skipping data and save power consumption. As shown in
Figure 10, it pre-reads 40 seconds worth of sound data in a few
seconds (read data is stored to DRAM for replay at normal
speed). During the remaining time it turns off unneeded control
circuits to save the battery (power consumption). Since all the
