PUI Audio, Inc. DMM-4026-B-I2S-EB-R

PUI Audio is proud to introduce a series of high-fidelity MEMS wideband microphones covering the full audio spectrum from 20 Hz to 18 kHz, with select models extending to 20 kHz, and ±1 dB consistency across the entire frequency response range. This evaluation board enables rapid testing and prototyping of the I²S DMM-4026-B-I2S-R. Solder pads make connecting to the evaluation board fast and easy. For proper microphone operation, the I2S converter must support a 32-bit word length for mono operation and a 64-bit word length for stereo operation with two microphones. Each microphone outputs 24-bit data with 18-bit resolution, where six bits are zero-padded (0). The microphone's frequency response and sensitivity deviation must not exceed ±3 dB.

• Covers 20 Hz to 18 kHz audio band, up to 20 kHz for select models
• ±1 dB consistency across the entire frequency response range
• I2S converter supports 32-bit word length in mono operation and 64-bit word length in stereo operation
• Each microphone outputs 24-bit data with 18-bit accuracy and six zero-value bits
• Frequency response and sensitivity deviation within ±3 dB
