Key Features
- 75 dB minimum common-mode rejection ratio (CMRR) for effective noise suppression in balanced audio lines
- 3 MHz bandwidth enabling high-fidelity signal reception across professional audio and instrumentation bands
- ±18V supply voltage range for compatibility with standard professional audio signal levels
Applications
The SSM2141SZ is designed for professional audio applications requiring balanced line reception, such as mixing consoles, studio interfaces, and broadcast equipment. Its high CMRR of 75 dB minimum effectively rejects common-mode noise picked up over long cable runs in live sound and recording environments. The device is also suitable for instrumentation amplifier front-ends where differential signal integrity is critical.

Frequently Asked Questions
What common-mode rejection ratio does the SSM2141SZ achieve in balanced audio applications?
The SSM2141SZ provides a minimum CMRR of 75 dB, with typical values higher, ensuring that noise and interference injected equally on both balanced lines is effectively suppressed, maintaining signal integrity over cable runs of 100 meters or more in professional audio installations.
Can the SSM2141SZ handle the ±18V rails used in professional studio equipment?
Yes, the SSM2141SZ operates with a negative supply voltage limit of up to -18V, making it fully compatible with the dual ±15V or ±18V power supplies common in professional mixing consoles, outboard gear, and studio interfaces without requiring level-shifting circuits.
What is the bandwidth of the SSM2141SZ and how does it affect audio signal quality?
The SSM2141SZ has a 3 MHz bandwidth at -3dB, which is far beyond the 20 kHz audio band, ensuring flat frequency response and minimal phase shift across the full audio spectrum from 20 Hz to 20 kHz for transparent, high-fidelity balanced line reception.
For a studio mic preamp design, how does SSM2141SZ compare to a discrete balanced receiver built from a general-purpose op-amp?
The SSM2141SZ delivers a guaranteed 75 dB CMRR with matched internal resistor pairs, while a discrete op-amp solution requires precision 0.1% matched external resistors and careful layout to achieve similar CMRR. The integrated solution reduces component count, saves 8-pin board space, and ensures consistent production performance.
