ADMP504 Evaluation Board

EVAL-ADMP504Z-FLEX UltraLow Noise Microphone with Bottom Port and Analog Output Evaluation Board

TDK InvenSense

The EVAL-ADMPxxxZ-FLEX is a simple evaluation board that allows quick evaluation of the performance of analog MEMS microphones in a package with a 3.35 mm × 2.50 mm footprint size. The small size and low profile of the flexible PCB enables direct placement of the microphone into a prototype or an existing design for an in situ evaluation. The evaluation board consists of a bottom port microphone soldered to a flexible PCB with color-coded wires attached. The only other component on the board is a 0.1µF supply bypass capacitor.

Product Description

The ADMP504 is a high performance, very low noise, low power, analog output, bottom-ported omnidirectional MEMS microphone. The ADMP504 consists of a MEMS microphone element, an impedance converter and an output amplifier. The ADMP504 sensitivity specification makes it an excellent choice for both near field and far field applications.
