Description

The WM8972L is a low power, high quality mono CODEC designed for portable digital audio applications.


The device integrates complete interfaces to mono microphones. External component requirements are drastically reduced as no separate microphone amplifiers are required. Advanced on-chip digital signal processing performs graphic equaliser and automatic level control for the microphone or line input.


The WM8972L can operate as a master or a slave, with various master clock frequencies including 12 or 24MHz for USB devices, or standard 256fs rates like 12.288MHz and 24.576MHz. Different audio sample rates such as 96kHz,48kHz, 44.1kHz are generated directly from the master clock without the need for an external PLL.


The WM8972L operates at supply voltages down to 1.8V, although the digital core can operate at voltages down to 1.42V to save power, and the maximum for all supplies is 3.6 Volts. Different sections of the chip can also be powered down under software control.


The WM8972L is supplied in a very small and thin 5x5mm QFN package, ideal for use in hand-held and portable systems.
