This datasheet mainly introduces the function characteristics and application scenarios of SSM2142.
The SSM2142 is an integrated differential‑output buffer amplifier that converts a single‑ended input to a balanced output pair. It provides transformer‑like balanced output, drives 10 V RMS into a 600 Ω load, and maintains low distortion (0.006 % THD+N) across 20 Hz‑20 kHz.
Designed for audio mixers, distribution amplifiers and other hi‑fi equipment, the device features a high slew rate (15 V/µs), short‑circuit protection, and on‑chip laser‑trimmed resistors for excellent common‑mode rejection. It is supplied in an 8‑lead PDIP or 16‑lead SOIC package and operates from ±13 V to ±18 V supply voltages.
