GENERAL DESCRIPTION
The SSM-2220 is a dual low noise matched PNP transistor which has been optimized for use in audio applications.
The ultra-low input voltage noise of the SSM-2220 is typically only 0.7nV/√KHzover the entire audio bandwidth of 20Hzto 20kHz. The low noise, high bandwidth (190MHz), and Offset Voltage of (200μV Max) make the SSM-2220 an ideal choice for demanding low noise preamplifier applications.
The SSM-2220 also offers excellent matching of the current gain (ΔhFE) to about 0.5% which will help to reduce the high order amplifier harmonic distortion.In addition, to insure the long-term stability of the matching parameters, internal protection diodes across the base-emitter junction were used to clamp any reverse base-emitter junction potential.This prevents a base-emitter breakdown condition which can result in degradation of gain and matching performance due to excessive breakdown current.
Another feature of the SSM-2220 is its very low bulk resistance of 0.32 typically which assures accurate logarithmic conformance.
The SSM-2220 is offered in 8-pin plastic, dual-in-line. and SO and its performance and characteristics are guaranteed over the extended industrial temperature range of -40℃ to +85℃.
