PRODUCT DESCRIPTION

The MAT04 is a quad monolithic NPN transistor that offers ex-

cellent parametric matching for precision amplifier and nonlin-

ear circuit applications. Performance characteristics of the

MAT04 include high gain (400 minimum) over a wide range of

collector current, low noise (2.5 nV/

√Hz maximum at 100 Hz,

MAT04 also features a low offset voltage of 200

µV and tight

current gain matching, to within 2%. Each transistor of the

MAT04 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 25

°C and over the industrial and military temperature ranges.

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 match-

ing characteristics due to reverse bias base-emitter current.

The superior logarithmic conformance and accurate matching

characteristics of the MAT04 makes it an excellent choice for

use in log and antilog circuits. The MAT04 is an ideal choice in

applications where low noise and high gain are required.
