An ISD17240SYR is an integrated circuit (IC) chip within the family of integrated interface-voice recording & playback ICs available. This versatile and comprehensive IC delivers standard playback modes, as well as loop, erase, program and erase-protect capabilities. ISD17240SYR chips offer 60-second maximum recording time and are designed for use with 4V-30V power supplies. They feature quick start playback capability and are ideal for use in applications such as security systems, interactive kiosks and voice mail.

The ISD17240SYR chip is built to record and play back audio signals from 10Hz to 10kHz. Its programmable record modes enable multiple configurations such as single shot, or programmed looping or modulation record. In addition, it offers external trigger capability and adjustable input gain control. The chip also features erase protection, which prevents a recording from being erased. This feature is particularly useful in applications such as security systems, which could benefit from a recording acting as evidence.

The chip operates on analogue input signals and consists of several components, including microphones, amplifiers, A/D converters, memory elements and power supply regulation. When recording, the audio signal is first amplified and then converted from analogue to digital by the A/D converter. The digital signal is then stored in the ICs memory elements for recording. During playback, the signal is retrieved from the ICs memory and the D/A converter converts it back to analogue.

The ISD17240SYR is easy to integrate into a variety of projects. Its single 3.3V+5V dual-supply design makes it compatible with systems that require low-power operation, while its small form factor makes it suitable for space-constrained install applications. In addition, the chip is resistant to electro-static discharge (ESD), radiation and surge interference, making it perfect for use in embedded systems.

The ISD17240SYR chip is an ideal choice for projects requiring stand-alone, low power audio recording and playback capabilities. Its versatile design and integrated components make it particularly suitable for security systems, interactive kiosks and voice mail applications.
