MAT14ARZ-R7

MAT14 is a quad monolithic NPN transistor that offers excellent parametric matching for precision amplifier and nonlinear circuit applications. Each transistor of the device 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. 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 device make it an excellent choice for use in log and antilog circuits. It is used in application such as low noise op-amp front end, current mirror and current sink/source, low noise instrumentation amplifiers, voltage controlled attenuators, log amplifiers etc.
