The ISD1760SY is a cost-effective single-chip voice record/playback device that is ideal for applications like answering machines and interactive toys. It has high quality, non-volatile storage that allows it to be used without a microcontroller and also provides seamless recording and playback operation. This makes it perfect for applications that require long-term recording/playback capabilities with minimal power consumption and no memory degradation.

Features

The ISD1760SY features a single-chip, high performance, 8-bit A/D converter and an on-board flash memory. It is designed to provide high quality, non-volatile storage for up to 64 minutes of speech recording and playback. It also has a low-power consumption architecture that allows it to operate at full power for up to 16 hours without the need for external power supply. The device comes in an LQFP-48 package for easy integration into compact designs.

Application Field

The ISD1760SY is ideally suited for applications such as interactive toys, talking books and electronic dictionaries, talking clocks, answering machines, sports and portable audio players, educational games, datasheets and manual page readers, and many others. It can also be used in mobile phones and PDAs, as well as industrial, automotive, and medical applications.

Working Principle

The ISD1760SY works by converting an incoming analog signal into a digital signal that is stored in its on-board flash memory. It can then playback this stored signal, allowing voice record and playback applications without the need for a microcontroller. The ISD1760SY can be easily interfaced with a microcontroller or ASIC to provide a record/playback system that can be tuned according to user requirements.

The ISD1760SY has an on-board programmable gain amplifier and a built-in headphone driver for low-power playback of the stored analog signal. It also has an 8-bit ADC with a sample rate of 8 kHz and an on-board timer for programmed or manual audio file playback. The ISD1760SY is also designed to provide low noise and drift-free audio recording.

Conclusion

The ISD1760SY provides a cost-effective, low-power solution for voice record and playback applications. It offers high-quality audio storage and playback with minimal power consumption, making it ideal for a wide range of applications. It can easily be interfaced with a microcontroller or ASIC to provide a record/playback system that can be tailored to specific user requirements.
