WM9711L General Description
The WM9711L is a highly integrated input / output device designed for mobile computing and communications. The device can connect directly to mono or stereo microphones,stereo headphones and a mono speaker, reducing total component count in the system. Additionally, phone input and output pins are provided for seamless integration with wireless communication devices.
The WM9711L also offers five GPIO pins for interfacing to buttons or other digital devices. To monitor the battery voltage in portable systems, the WM9711L has two uncommitted comparator inputs.
All device functions are accessed and controlled through a single AC-Link interface compliant with the AC'97 standard.Additionally, the WM9711L can generate interrupts to indicate low battery, dead battery, thermal cut-out and GPIO conditions.
The WM9711L operates at supply voltages from 1.8 to 3.6 Volts. Each section of the chip can be powered down under software control to save power. The device is available in a small leadless 7x7mm QFN package, ideal for use in handheld portable systems, or in the industry standard 48-pin TQFP package.
