SPM0408LE5H-TB-6

Overview

The SPM0408LE5H-TB-6 is a miniature, high-performance, low-power bottom-port silicon microphone utilizing SiSonic MEMS technology. It integrates an acoustic sensor, low-noise input buffer, and output amplifier. The device operates up to 5V with enhanced RF protection and offers adjustable gain from 0dB to 20dB via external components. It features omnidirectional directivity, flat frequency response, and zero-height packaging for space-constrained portable electronics.

Feature Summary

• Integrated low-noise input buffer and output amplifier
• Enhanced RF immunity for reliable operation in noisy environments
• Adjustable gain configuration using external resistors and capacitors
• Zero-height package design suitable for ultra-thin devices

Applications

• Cellphones and smartphones
• Laptop computers
• Digital still cameras
• Portable music recorders

Procurement Notes

Verify the -6 suffix indicates a 13-inch reel containing 4,800 units per EIA-481 tape and reel standard. Confirm moisture sensitivity level is Class 1 and shelf life is twelve months when stored in factory-supplied unopened ESD bags under maximum conditions of 30°C and 70% relative humidity. Ensure compliance with RoHS directive 2011/65/EC and halogen-free standards.

Selection Notes

Select this component for applications requiring wideband audio performance and superior RF immunity. The integrated amplifier allows for flexible gain settings between unity and 20dB through user-defined R1 and C1 values. The bottom-port architecture supports zero-height integration, making it ideal for compact consumer electronics where board real estate is limited.

Part Context

This part belongs to the SiSonic family of amplified surface-mount silicon microphones. It shares core MEMS technology with other models but distinguishes itself through enhanced RF protection and specific zero-height mechanical dimensions. The product line targets portable electronic devices demanding high acoustic fidelity within strict physical constraints.

FAQ

How is the gain adjusted on the SPM0408LE5H-TB?

Gain is set by connecting the GAIN pin to the OUTPUT pin for unity gain (0dB), or by configuring external resistor R1 and capacitor C1 to achieve up to 20dB of gain.

What are the absolute maximum voltage ratings?

The VDD to Ground rating is -0.5V to +7.0V, and the OUT to Ground rating is -0.3V to VDD + 0.3V.
