The WM8974CGEFL/RV is a low power, high-quality mono CODEC designed for portable applications such as digital still cameras and audio recorders. It supports audio sample rates ranging from 8 kHz to 48 kHz, with a DAC signal-to-noise ratio (SNR) of 98 dB and total harmonic distortion (THD) of -84 dB, and an ADC SNR of 94 dB with a THD of -83 dB. The device features an on-chip headphone/speaker driver capable of delivering 40 mW into 16Ω and 0.9 W into 8Ω, along with a mono line output. The WM8974CGEFL/RV includes programmable microphone preamps with differential or single-ended inputs, low-noise bias for electret microphones, and advanced digital filtering options such as a 5-band equalizer, automatic level control, and noise gate. It operates at supply voltages from 2.5V to 3.6V, with digital supplies down to 1.71V, and features a small 4x4 mm QFN package, making it suitable for space-constrained designs. The device is ideal for applications requiring high-quality audio processing with minimal external components.
