GENERAL DESCRIPTION
The SSM2212 is a dual, NPN-matched transistor pair that is specifically designed to meet the requirements of ultralow noise audio systems.
With its extremely low input base spreading resistance (rbb is typically 28 Ω) and high current gain (hFE typically exceeds 600 at IC = 1 mA), the SSM2212 can achieve outstanding signal-tonoise ratios. The high current gain results in superior performance compared to systems incorporating commercially available monolithic amplifiers.
