PRODUCT DESCRIPTION
verified to meet stated limits. Device performance is guaranteed
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,
IC = 1 mA) and excellent logarithmic conformance. The
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
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.
