MAT14

Matched Monolithic Quad Transistor

Product Details

The MAT14 is a quad monolithic NPN transistor that offers excellent parametric matching for precision amplifier and nonlinear circuit applications. Performance characteristics of the MAT14 include high gain (300 minimum) over a wide range of collector current, low noise (3 nV/√Hz maximum at 100 Hz, IC = 1 mA), and excellent logarithmic conformance. The MAT14 also features a low offset voltage of 100 μV typical and tight current gain matching to within 4%. Each transistor of the MAT14 is individually tested to data sheet specifications. For matching parameters (offset voltage, input offset current, and gain match), each of the dual transistor combinations are verified to meet stated limits. Device performance is guaranteed at an ambient temperature of 25°C and over the industrial temperature range.

The long-term stability of matching parameters is guaranteed by the protection diodes across the base emitter junction of each transistor. These diodes prevent degradation of beta and matching characteristics due to reverse bias, base emitter current. The superior logarithmic conformance and accurate matching characteristics of the MAT14 make it an excellent choice for use in log and antilog circuits. The MAT14 is an ideal choice in applications where low noise and high gain are required.

APPLICATIONS

  • Low noise op amp front end
  • Current mirror and current sink/source
  • Low noise instrumentation amplifiers
  • Voltage controlled attenuators
  • Log amplifiers

So far this has exceeded expectations in our groups design and testing phase. It is our speculation that during future rigorous testing it will continue to exceed our needs.

Great features for audio high-end world ...
This quad monolithic NPN transistor is very good for using as current mirror and low noise audio input stage. A PDIP-14 version would be highly appreciated, including a PNP version.
