GENERAL DESCRIPTION
The SSM2017 is a latest generation audio preamplifier combin-
ing SSM preamplifier design expertise with advanced process-
ing. The result is excellent audio performance from a self-
contained 8-pin mini-DIP device, requiring only one external
gain set resistor or potentiometer. The SSM2017 is further en-
hanced by its unity gain stability.
Key specifications include ultralow noise (1.5 dB noise figure)
and THD (<0.01% at G = 100), complemented by wide band-
width and high slew rate.
Applications for this low cost device include microphone pream-
plifiers and bus summing amplifiers in professional and con-
sumer audio equipment, sonar, and other applications requiring
a low noise instrumentation amplifier with high gain capability.
