SPK0415HM4H-B

Digital High-SNR SiSonic^TMMicrophone

The SPK0415HM4H-B is a miniature, high-

performance, low power, top port silicon

digital microphone with a single bit PDM

output. Using Knowles’ proven high

Features:

• Low Noise

• Low Current

• RF Shielded

performance SiSonic^TMMEMS technology,

the SPK0415HM4H-B consists of an acoustic

sensor, a low noise input buffer, and a

sigma-delta modulator. These devices are

suitable for applications such as cellphones,

smart phones, laptop computers, sensors,

digital still cameras, portable music

• PDM Output

• Supports Dual Multiplexed Channels

• Ultra-Stable Performance

• Standard SMD Reflow

• Omnidirectional

recorders, and other portable electronic

devices where excellent audio performance

and RF immunity are required. The high

Signal-to-Noise-Ratio (SNR) of the

SPK0415HM4H-B enhances the performance

of far-field applications and many complex,

multi-microphone algorithms.
