AK4940 - 24-bit Mono CODEC

General Description

The AK4940 is an audio CODEC with gain amplifier for microphone and analog direct path.

It is ideal for data communication modules (DCM).

The AK4940 is available in small 24-pin QFN (4 mm  4 mm, 0.5 mm pitch) package.

Key Features

  • ADC: 24-bit Monaural ADC (with Microphone Gain Amplifier) - Sampling Frequency: fs = 8kHz to 48kHz - Analog Gain Amplifier for Microphones (-6 to 27dB, 3dB step) - Analog Input Selector - Differential Input/ Single-ended Input/ Pseudo Differential Input - ADC Characteristics: S/(N+D):80dB, S/N:90dB (fs=48kHz, Differential Input, MIC Gain=0dB) - Digital Volume (+24 to -103dB, 0.5dB Step, Mute) - Digital HPF for DC Offset Cancelling - Two Kinds of Digital Filters: Sharp Roll-Off Filter,.
