ISD5116S

The ISD5116S from Nuvoton Technology is a fully integrated, single-chip voice record and playback solution designed for messaging applications. It provides high-quality audio recording and playback capabilities, ideal for portable products like cellular phones, automotive communication systems, and GPS navigation devices.

This device supports recording durations ranging from 8 minutes 44 seconds up to 17 minutes 28 seconds, with a sampling frequency between 4 and 8kHz. It features an I2C serial port for control and duration selection, minimizing pin count. The ISD5116S integrates essential analog functions including automatic gain control (AGC), volume control, and a power amplifier/speaker driver, simplifying interface with other chipsets.

Designed for flexibility, the ISD5116S operates within a supply voltage range of 2.7V to 3.3V. It supports both analog and digital data storage, allowing for phone book numbers and configuration parameters to be stored alongside voice messages. The IC is housed in a 28-SOIC surface mount package, suitable for various electronic designs. Its operating temperature range is from 0°C to 70°C (TA).

Key features include Auto Mute, Automatic Gain Control, Digital Data Storage, and Volume Control, enhancing its functionality for diverse applications. The input signal can be analog single-ended or from a microphone, with output signals including analog single-ended, analog differential, and PWM speaker output. The filter pass band is between 1.7kHz and 3.4kHz.
