GENERAL DESCRIPTION
The SSM2019 is a latest generation audio preamplifier, combin-
ing 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.
