LT3092EST

200mA 2-Terminal Programmable Current Source

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.
