GENERAL DESCRIPTION

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, I_C= 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 tem-

perature 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.
