The SSM2019 is a latest generation audio preamplifier, combining SSM preamplifier design expertise with advanced processing.
The SSM2019 is a self‑contained audio preamplifier designed for microphone, intercom, paging, two‑way radio, sonar and digital audio applications. It offers excellent noise performance, ultra‑low distortion, and a wide 1 MHz bandwidth at a gain of 100, while remaining inexpensive and available in PDIP or SOIC packages.
Key features include a typical voltage noise density of 1 nV/√Hz, THD+N below 0.01 % at high gain, a slew rate of 16 V/ps, and a maximum gain of 70 dB. The device operates from a supply voltage range of 4.5 V to +18 V and provides true differential inputs with optional phantom powering for microphones.
