This datasheet provides the characteristics and parameters of the SSM2143 device
The SSM2143 is an integrated differential amplifier designed for balanced audio line inputs, offering high common‑mode rejection and ultralow distortion. It provides a typical 90 dB CMR and a slew rate of 10 V/µs, with a wide 7 MHz bandwidth when set to a gain of ½.
The device can operate from a 6 V to 18 V supply and supports input levels up to +28 dBu. It is offered in 8‑pin plastic DIP and SOIC packages and can be paired with the SSM2142 driver to form a full line‑driver/receiver system with unity gain.
| Common‑Mode Rejection (CMR) | 90 dB typ (60 Hz) |
|---|---|
| Total Harmonic Distortion + Noise (THD+N) | 0.0006 % typ @ 1 kHz |
| Slew Rate | 10 V/µs typ |
| Bandwidth (G = ½) | 7 MHz typ |
| Gain Options | G = ½ or G = 2 |
| Supply Voltage Range | +6 V to +18 V |
The device provides a typical common‑mode rejection of 90 dB at 60 Hz.
It offers two gain levels: a gain of ½ (default) or a gain of 2 by swapping the +IN/‑IN and SENSE/REFERENCE connections.
The input stage can handle signals as large as +28 dBu when set to a gain of ½.
The part is available in an 8‑pin plastic DIP (P suffix) and an 8‑pin SOIC (S suffix).
