I8102SYI
ISD8102SYI 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.
ISD8102SYI output can be configured to drive either single ended or bridge tied loads (BTL). The Mode pin controls which configuration is active. This function is useful when using ISD8102SYI to alternate between driving a speaker or a mono earpiece.
