WM8972L - MONO CODEC FOR PORTABLE AUDIO APPLICATIONS

General 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.

Key Features

  • DAC SNR 98dB (‘A’ weighted), THD.
  • 84dB at 48kHz, 3.3V.
  • ADC SNR 95dB (‘A’ weighted), THD -82dB at 48kHz, 3.3V.
  • Complete Mono Microphone Interface - Programmable ALC / Noise Gate.
  • On-chip 400mW BTL Speaker Driver (mono).
  • Digital Graphic Equaliser.
  • Low Power - 7mW mono playback (1.8V / 1.5V supplies) - 14mW record & playback (1.8V / 1.5V supplies).
  • Low Supply Voltages - Analogue 1.8V to 3.6V - Digital core: 1.42V to 3.6V - Digi.

w WM8972L Mono CODEC for Portable Audio Applications 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.
