Smart Home Audio(325)




ISD8101RYI is a general purpose analog audio amplifier capable of driving an 8-ohm load with up to 1.5Wrms output power. This device includes current limiting and a chip enable pin with low standby current and excellent pop-and-click performance.

Also included is the ability for the inputs to be configured as either single-ended or differential.  Internal resistors set the device gain at 20dB. With external resistors, any gain less than 20dB can be achieved.  The device is unity gain stable, including when used with external feedback resistors and external capacitors as may be optionally used for implementing simple filtering functions.

Target Applications:

Portable Audio Device/ Speaker
Greeting Cards
Home Appliance
