ISD8104SYI

ISD8104SYI

ISD8104SYI is a general-purpose analog audio amplifier, capable of driving a 4 Ω load with up to 2 Wrms output power. This device includes output current limiting, chip enable, low standby current and excellent pop-and-click suppression.

The device's gain can be set up to 20 dB by internal resistors, and with external resistors any gain less than this can be achieved.  The device is unity gain stable, including use with external feedback resistors and external capacitors as may be optionally used for implementing simple filtering functions.

ISD8104SYI has differential inputs and can be configured to accept either single ended or differential signals.

Target Applications:

•  Toy
Portable Audio Device/ Speaker
Greeting Cards
Boombox
