1 voice chip - ISD1900 Features
- Wide operating voltage (2.4V ~ 5.5V), adjustable and provides a high sampling frequency (4kHz ~ 12kHz).
- high-quality single-chip voice, reduce material costs and shorten product development time to market, multi-recording button is the best solution.
- provides two operating modes: enter the start and end address, used to trigger a number of different length information; provide up to eight with a similar length of the information and triggered by the eight buttons.
- No need for any micro-controller and the editing process so that engineers can quickly and easily add voice capabilities of its products, and in the shortest possible time, with the lowest materials cost product launch.
- voice broadcasting and recording control system: the analog signal can be transmitted directly from the microphone to an external speaker for voice broadcasting and monitoring.
- replace the old voice recording chip (for example, has stopped production and theISD1400 ISD2500 series), so the customer does not require substantial changes to keep the existing operating functions. ISD1900 for 28-pin SOIC lead-free package, its process and function also applies to ISD14B00 products. ISD14B00 series with the only difference is ISD14B00 ISD1900 series provide easy DIE other manufacturers to its package.
