Additional Details

The APA2176OI-TRG typically operates from a supply voltage of 2.5V to 5.5V. It offers a signal-to-noise ratio (SNR) of typically 90dB. The device is available in a compact package, such as a QFN or similar surface-mount package. It also features a shutdown mode to further reduce power consumption when the amplifier is not in use. The gain can often be adjusted using external resistors, giving designers flexibility to match the amplifier's output to the speaker's sensitivity.
