What are the key features of SSM2143PZ?
- Greater than 90 dB common-mode rejection ratio rejecting hum and interference on balanced audio lines
- Wide ±6 V to ±18 V dual supply range compatible with standard ±15 V professional audio rails
- Unity-gain differential input designed to bridge balanced XLR to unbalanced RCA consumer interfaces
What is SSM2143PZ used for?
The SSM2143PZ is used in professional audio equipment such as mixing consoles, patchbays, and studio monitor controllers that require high-fidelity balanced-to-unbalanced conversion. Its greater than 90 dB CMRR eliminates ground loop hum and RF noise picked up over long cable runs in live sound and broadcast installations. Consumer audio interface adapters, mastering equipment, and DA converters also use the SSM2143PZ to accept balanced inputs from professional sources.

Frequently Asked Questions
How does SSM2143PZ's common-mode rejection ratio benefit long cable runs in professional audio setups?
SSM2143PZ achieves greater than 90 dB common-mode rejection ratio at 60 Hz, which attenuates 120 V mains-frequency hum and RF interference coupled onto balanced cables by over 30,000 times relative to the differential audio signal. This allows cable runs exceeding 100 meters without audible noise in broadcast or live-sound installations.
What supply voltage range does SSM2143PZ require, and is it compatible with standard ±15 V pro-audio rails?
SSM2143PZ operates from ±6 V to ±18 V dual supply, with a nominal rating of ±15 V that is the de facto standard in professional audio rack equipment. It is fully compatible with standard ±15 V rails found in mixing consoles, outboard gear, and studio patchbays without any voltage conversion.
When should a designer choose SSM2143PZ over a general-purpose op-amp for balanced line reception?
SSM2143PZ should be chosen over a discrete op-amp circuit when designers need better than 90 dB CMRR with minimal component count. A discrete difference amplifier requires 4 precision 0.1%-matched resistors to approach 80 dB CMRR, while SSM2143PZ achieves 90 dB or more with its internal trimmed network, saving 4 BOM components and approximately 30 minutes of calibration per channel.
