LT3092MPST 数据手册 ( 数据表 ) - Linear Technology

DESCRIPTION
The LT®3092 is a programmable 2-terminal current source. It requires only two resistors to set an output
current between 0.5mA and 200mA. A multitude of analog techniques lend themselves to actively programming the output current. The LT3092 is stable without input and output capacitors, offering high DC and AC impedance. This feature allows operation in intrinsically safe applications.
