SSM2220

Audio Dual Matched PNP Transistor

Product Details

The SSM2220 is a dual PNP matched transistor which has been optimized for use in audio applications.

The ultra-low input voltage noise of the SSM2220 is typically only 0.7 nV/√Hz over the entire audio bandwidth of 20 Hz to 20 k Hz. The low noise, high bandwidth (190 MHz), and Offset Voltage of 200 u V Max)make the SSM2220 an ideal choice for demanding low noise preamplifier applications.

The SSM2220 also offers excellent matching of the current gain (ΔhFE) to about 0.5%, which helps to reduce the high order ampli-fier harmonic distortion. In addition, to ensure the long-term stability of the matching parameters, internal protection diodes across the base to emitter junction were used to clamp any reverse base to emitter junction potential. This prevents a base to emitter breakdown condition, which can result in degradation of gain and matching performance due to excessive breakdown current.

The SSM2220 is offered in 8-lead plastic dual inline (PDIP) and 8-lead standard small outline (SOIC), and its performance and characteristics are guaranteed over the extended industrial temper-ature range of −40°C to +85°C.
