NAU8500 - 24-bit Mono Audio ADC

General Description

NAU8500 is a cost effective and low power wideband MONO audio ADC.

This device integrates a broad range of additional functions to simplify the implementation of complete audio systems.

Key Features

  • voice band digital filtering. NAU8500 operates at supply voltages from 2.5V to 3.6V, although the digital core can operate at voltage as low as 1.71V to save power. The NAU8500 is specified for operation from -40°C to +85°C, and is availabl.

NAU8500 1. GENERAL DESCRIPTION 24-bit Mono Audio ADC with 2-wire Interface Control emPowerAudio™ NAU8500 is a cost effective and low power wideband MONO audio ADC. This device integrates a broad range of additional functions to simplify the implementation of complete audio systems. Functions include Automatic Level Control (ALC) with noise gate, PGA, standard audio interface I2S, PCM with time slot assignment, and on-chip PLL. The device provides one differential microphone input and few variable gain control stages in the audio path. The analog inputs have PGA on the front end, allowing dynamic range optimization with a wide range of input sources. In addition to a digital high pass filter to remove DC offset voltages, the ADC also features voice band digital filtering.
