I8104RYI

ISD8104_Diagram

 

ISD8104RYI are a general purpose analog audio amplifier, capable of driving a 4Ω load with up to 2Wrms output power. This device includes output current limiting, chip enable, low standby current and excellent pop-and-click suppression.

Internal resistors set the device to have default 20dB gain, 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.

ISD8104RYI 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
Home Appliance
