MAT14中文资料亚德诺数据手册PDF规格书

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, 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.
