Key Features
- 20 dB fixed preamplifier gain with 20 kHz audio bandwidth for full-range voice and music capture
- Integrated noise gate suppresses background noise below threshold, improving signal clarity without external DSP
- Dynamic range compression in a single 14-pin SOIC reduces component count versus discrete mic preamp designs
Applications
The SSM2166S-REEL suits conference systems and hands-free speakerphones where a microphone signal must be amplified and dynamically compressed before transmission or codec input. Its on-chip noise gate is valuable in voice-activated devices such as smart speakers and intercom units, automatically muting low-level background noise between utterances. It is also used in PA system input stages and portable audio recorders where consistent, processed audio is needed from a single compact IC.

Frequently Asked Questions
What gain and bandwidth does the SSM2166S-REEL provide for microphone preamplification?
The SSM2166S-REEL delivers a fixed 20 dB of gain and covers a 20 kHz audio bandwidth, making it well matched to electret microphone capsules and condenser elements used in voice and near-field recording applications. This gain level raises a typical microphone output of a few millivolts to a line-compatible level without requiring external amplification stages.
How does the built-in noise gate in SSM2166S-REEL benefit a hands-free speakerphone design?
The integrated noise gate monitors the input signal level and attenuates the output when the signal falls below a set threshold, typically suppressing ambient noise below -40 dBu during silence. In a speakerphone, this prevents fan noise, HVAC hum, and room echo from being continuously transmitted, improving intelligibility for remote participants without requiring a separate DSP or software voice-activity detection algorithm.
What is the package style of SSM2166S-REEL and how does the tape-and-reel suffix affect ordering?
The device uses a 14-pin SOIC package with a 0.25-inch body width, compatible with standard SMT reflow assembly. The REEL suffix indicates the parts are shipped on a 2500-unit tape-and-reel, which suits automated pick-and-place production. For prototyping quantities below 100 units, a tube or cut-tape variant may reduce minimum order cost.
