Frequently Asked Questions
What common-mode rejection ratio does SSM2141SZ-REEL provide, and why does that matter for balanced audio?
SSM2141SZ-REEL delivers a minimum CMRR of 75 dB, which means common-mode noise such as 50 Hz or 60 Hz hum picked up on a balanced cable is attenuated by more than 75 dB relative to the differential signal. This level of rejection is sufficient for studio-grade balanced interconnects running up to 50 metres, maintaining signal fidelity on a ±18 V dual supply without additional filtering.
Which supply voltage range does SSM2141SZ-REEL require for professional audio applications?
The device operates with a negative supply up to -18 V and a corresponding positive rail, allowing a full ±18 V dual-supply configuration standard in professional audio equipment. Designers can also run it at lower supply voltages down to approximately ±5 V, trading output swing for reduced power consumption, while the 3 MHz bandwidth remains adequate for the 20 Hz to 20 kHz audio band with more than 100× headroom.
How does SSM2141SZ-REEL compare to SSM2143 in terms of CMRR and intended use?
SSM2141SZ-REEL provides 75 dB minimum CMRR at audio frequencies and is optimised for general professional balanced-line reception in mixing desks and interfaces. SSM2143 targets higher CMRR at wider bandwidths and is designed for applications requiring tighter than 90 dB rejection. When cost and standard 3 MHz bandwidth are acceptable and the dual ±18 V supply is available, SSM2141SZ-REEL is the more economical 8-pin SOIC choice.
Can SSM2141SZ-REEL be used in industrial sensor signal conditioning?
Yes, SSM2141SZ-REEL suits industrial instrumentation front ends where differential signals from sensors or transmitters travel over shielded twisted-pair cables. Its 75 dB CMRR suppresses ground-loop interference common in factory environments, and its 3 MHz bandwidth accommodates sensors with outputs up to several hundred kilohertz. The ±18 V supply compatibility and low 2500 µV maximum input offset support accurate, low-drift signal conditioning across industrial temperature ranges.
