Note: The T5818 is marked as EOL and is not recommended for new designs.
The T5818 is a Pulse Density Modulation (PDM) microphone with a dynamic range of 107dB at 590µA, the widest dynamic range in the industry at the lowest power, which allows for excellent acoustic performance in environments that shift from very quiet to very loud, such as far field voice pickup barge-in for Smart Speaker applications.
This microphone features 66dBA SNR, 135dB SPL AOP, at 590 µA in High Quality Mode (HQM), and decreases power consumption to 215 µA in Low Power Mode (LPM). It is essential for capturing high quality audio inputs, which plays a vital role for AI engines and cloud-based applications that require a PDM microphone interface. Current analog output wide dynamic range microphones require expensive ADCs to take advantage of full acoustic capabilities. The T5818 provides this ADC conversion while maintaining excellent dynamic range with the benefits of a PDM low latency bit stream, making it suitable for a wide range of applications, from mobile phones to ANC headsets.
