MAT02S:  Aerospace Low Noise, Matched Dual NPN Transistor

Product Details

The design of the MAT02 series of NPN dual monolithic transistors is optimized for very low noise, low drift, and low rBE. ADI's exclusive Silicon Nitride "Triple Passivation" process stabilizes the critical device parameters over wide ranges of temperature and elapsed time. Also, the high current gain (hFE) of the MAT02 is maintained over a wide range of collector current. Exceptional characteristics of the MAT02 include offset voltage of 50µV max. Device performance is specified over the full military temperature range.

Input protection diodes are provided across the emitter-base junctions to prevent degredation of the device characteristics due to reversed-biased emitter current. The substrate is clamped to the most negative emitter by the parasitic isolation junction created by the protection diodes. This results in complete isolation between the transistors.

The MAT02 should be used in any application where low noise is priority. The MAT02 can be used as an input stage to make an amplifier with noise voltage of less than 1.0nV/Hz at 100 HZ. Other applications such as log/anti-log circuits, may use the excellent logging conformity of the MAT02. Typical bulk resistance is only 0.3 Ohm to 0.4 Ohm. The MAT02 electrical characteristics approach those of an ideal transistor when operated over a collector current range of 1µA to 10mA.


  • Low Offset Voltage: 50µV max
  • Low Noise Voltage at 100 Hz, 1 mA:1.0 nV/√Hz max
  • High Gain (hFE):
    500 min at IC = 1 mA
    300 min at IC = 1 µA
  • Excellent Log Conformance:
    rBE about = 0.3 Ohms
  • Low Offset Voltage Drift
  • Improved Direct Replacement for LM194
