... Increasing the duration within a product series decreases the sampling frequency and bandwidth, which affects sound quality. Please refer to the ISD2500 Series Summary table on page 1-79 to compare filter pass band and product durations.

... A nonvolatile marker is automatically inserted at the end of each recorded message. It remains there until the message is recorded over. The EOM output pulses LOW for a period of T the end of each message. In addition, the ISD2500 Series has an internal V detect circuit to maintain message integrity CC should V goes LOW and the device is fixed in Playback-only mode ...
