INMP510: RF-Hardened Ultralow Noise Microphone with Bottom Port and Analog Output


InvenSense MEMS Microphone

The INMP510 is an RF-hardened, high performance, very low noise, low power, analog output, bottom-ported omnidirectional MEMS microphone. The INMP510 consists of a MEMS microphone element, an impedance converter and an output amplifier. The INMP510 sensitivity specification makes it an excellent choice for both near field and far field applications. The INMP510 is pin-compatible with the INMP504 microphone.

The INMP510 has very high SNR and extended wideband frequency response, resulting in natural sound with high intelligibility. Low current consumption enables long battery life for portable applications.

The INMP510 is available in an ultraminiature 3.35 mm × 2.5 mm × 0.98 mm surface-mount package.
