ADAU1977 Quad ADC

The ADAU1977 incorporates four high performance analogto-digital converters (ADCs) with direct-coupled inputs capable of 10 V rms. The ADC uses multibit sigma-delta (Σ-Δ) architecture with continuous time front end for low EMI. The ADCs can be connected to the electret microphone (ECM) directly and .
