ALFA RPAR AS3944-SMT Quad NPN Matched Transistor Array (SOIC-14)

The AS3944 is an array of 4 NPN transistor that offers excellent matching for precision amplifier and nonlinear applications. Performance characteristics include high gain over a wide range of collector current and Vcb, and excellent logarithmic conformance. The AS3944 also features of low offset voltage and tight current gain matching. Each transistor 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.

Logarithmic conformance and accurate matching characteristics makes the AS3944 an excellent choice for use in log and antilog circuits.
