What are the key features of SSM2143SZ?
- Fixed -6 dB gain differential receiver: accurately attenuates balanced line-level audio signals by 6 dB to match professional +4 dBu to consumer -10 dBV standards
- Wide supply range: operates from ±6 V to ±18 V dual supply covering professional audio equipment rails
- High CMRR: superior common-mode rejection ratio suppresses hum, ground noise, and cable-induced interference on balanced 3-wire audio connections
What is SSM2143SZ used for?
The SSM2143SZ is designed for professional audio equipment that receives balanced differential line signals from mixing consoles, preamplifiers, and studio interfaces, where it converts the +4 dBu balanced signal to a consumer -10 dBV unbalanced level with its fixed -6 dB gain. It is widely used in line-level input stages of audio power amplifiers, A/D converters, and digital audio workstation interfaces operating from ±15 V rails. Its high CMRR ensures clean audio performance even in electrically noisy environments with long cable runs.

Frequently Asked Questions
What is the gain and supply voltage range of the SSM2143SZ differential line receiver?
The SSM2143SZ provides a fixed -6 dB gain (voltage ratio of 0.5) for balanced differential audio inputs, and operates from a dual supply of ±6 V to ±18 V with a nominal ±15 V rail, covering virtually all professional audio equipment power supplies.
How does SSM2143SZ handle common-mode noise on a long balanced audio cable run?
The SSM2143SZ achieves high common-mode rejection ratio (CMRR) that attenuates noise signals simultaneously present on both conductors of a balanced pair — such as 50 Hz or 60 Hz mains hum picked up across cable runs of 10 m or more — while preserving the differential audio signal with minimal distortion at 20 Hz to 20 kHz.
When should an engineer use SSM2143SZ instead of a discrete op-amp difference amplifier for a balanced input stage?
Discrete op-amp difference amplifiers require four precision resistors matched to within 0.1% to achieve CMRR above 60 dB, whereas the SSM2143SZ integrates the resistor network on-chip with factory trimming, saving PCB area in an SOIC-8 footprint and reducing component count from 5 parts to 1 while maintaining consistent performance across -40°C to +85°C.
