SSM2212 - Analog Devices

SSM2212 Dual-Matched NPN Transistor

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-to-noise ratios. The high current .
