ISD4003-04MEDR

The ISD4003-04MEDR is a Voice Record and Playback IC (integrated circuit) mainly used in applications requiring recording and playback of audio signals. It offers a long battery lifetime, low power operation and high quality audio input and output. The ISD4003-04MEDR can be used in various applications such as audio books, MP3 players, digital voice recorders and other portable audio products.

The ISD4003-04MEDR is based on CMOS technology and is designed for low-voltage operation. It is used in applications requiring voice recording and playback. The integrated circuit features a wide operating voltage range of 2.0V to 5.0V and provides a maximum analog input and output range of 0.6V. The ISD4003-04MEDR has a total of 64 memory segments that can be used for recording and playback with a maximum sampling rate of 8kHz.

The ISD4003-04MEDR offers a selection of outputs to support data control signals or direct audio output. It provides digital outputs to control RECORD and STOP commands, multiple playback control signals, and direct PCM audio data output. The integrated circuit also includes a power amplifier to drive an audio output.The audio output can be connected directly to an 8Ω loudspeaker, while the loudspeaker output can drive a speaker up to 1Watt.The power amplifier can also be used as an input source for a microphone.

The ISD4003-04MEDR can be used with either analogue or digital recording. When recording analogue audio signals, the integrated circuit provides two TTL control lines for the RECORD and STOP commands. These control lines can be used to start recording, pause recording and end recording. The ISD4003-04MEDR also provides a single digital output that can be used for playback control. This output can be used to initiate playback, pause playback and stop playback.

For digital recording, the ISD4003-04MEDR offers two digital input lines for the CLOCK and MODE commands. This can be used to start recording, pause recording and end recording. The integrated circuit also includes a PCM output line that can be used to send the recorded audio data in digital format. This data can be used by other ICs or modules to process and store the audio signal.

The ISD4003-04MEDR is a cost effective and easy to use integrated circuit for applications requiring recording and playback of audio signals. It is simple to use and set up and offers high quality audio input and output. The integrated circuit is suitable for use in various applications such as audio books, MP3 players, digital voice recorders and other portable audio products.
