MAT12AHZ Datasheet PDF - ADI

The MAT12AHZ is a NPN dual-matched Bipolar Transistor Array specifically designed to meet the requirements of ultralow noise audio systems. It has extremely low input base spreading resistance and high current gain. It can achieve outstanding signal-to-noise ratios. The high current gain results in superior performance compared to systems incorporating commercially available monolithic amplifiers. Excellent matching of the current gain (ΔhFE) to about 0.5% and low VOS of less than 10µV typical make the MAT12 ideal for symmetrically balanced designs, which reduce high-order amplifier harmonic distortion. Stability of the matching parameters is guaranteed by protection diodes across the base emitter junction. These diodes prevent degradation of beta and matching characteristics due to reverse biasing of the base emitter junction. The device is also an ideal choice for accurate and reliable current biasing and mirroring circuits.
