The SSM2019 is the latest generation of audio preamplifiers, combining SSM preamplifier design expertise with advanced processing. The result is excellent audio performance from a monolithic device, requiring only one external gain set resistor or potentiom- eter. The SSM2019 is further enhanced by its unity gain stability. Key specifications include ultra-low noise (1.5 dB noise figure) and THD (<0.01% at G = 100), complemented by wide bandwidth and high slew rate. Applications for this low cost device include microphone pream- plifiers and bus summing amplifiers in professional and consumer audio equipment, sonar, and other applications requiring a low noise instrumentation amplifier with high gain capability.
The SSM2019 is a monolithic audio preamplifier designed for excellent noise performance with a typical voltage noise density of 1.0 nV/√Hz at 1 kHz and ultra-low total harmonic distortion (THD) of less than 0.01% at G=100. It features wide bandwidth, high slew rate, and unity gain stability, requiring only one external component to set the voltage gain.
