Description
The IS31AP4991A has been designed for demanding audio applications such as mobile phones and permits the reduction of the number of external components .It is capable of delivering 1.1W of continuous RMS output power into an 8? load @ 5V. An externally-controlled standby mode reduces the supply current to much less than 1µA. It also includes internal thermal shutdown protection. The unity-gain stable amplifier can be configured by external gain setting resistors.
- Operating from Vcc = 2.7V to 5.5V
- 1.1W output power @ Vcc = 5V, THD+N= 1%,f = 1kHz, with 8? load
- Ultra-low consumption in standby mode (muchless than 1µA)
- 56dB PSRR @217Hz in grounded mode
- Near-zero Click-and-pop
- Ultra-low distortion (0.074%@0.5W, 1kHz)
- SOP-8 and MSOP-8 package
