GENERAL DESCRIPTION
The SSM2220 is a dual, low noise, matched PNP transistor, which has been optimized for use in audio applications.
The ultralow input voltage noise of the SSM2220 is typically only 0.7 n V/√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 μV maximum) make the SSM2220 an ideal choice for demand ing, low...
