Key Features

Six capabilities built for the voice chainWhy JSM2718AB38CEP4-M0

High-SNR Pickup

The 63 dB(A) SNR keeps a low noise floor, preserving dynamic headroom for voice algorithms.

High AOP Headroom

An acoustic overload point of 126 dB SPL stays distortion-free in loud scenes.

Low Supply Current

A supply current of 125μA is friendly to battery-powered devices.

Compact Package

The 2.75 × 1.85 × 0.9 mm package suits space-constrained acoustic designs.

Lot-to-Lot Consistency

100% acoustic production test with SPC monitoring and full lot traceability.

Stable Volume Supply

Status: mass production — standing capacity and fast lead times.
