LT3092 200 mA 2-Terminal Programmable Current Source

Analog Devices' power management integrated circuit (PMIC) for driving sensors, remote supplies, and local supplies

Image of Analog Devices' LT3092 200 mA Terminal Progmmable Current SourceAnalog Devices' LT3092 is a programmable 2-terminal current source requiring only two resistors to set an output current between 0.5 mA and 200 mA. This current source is stable without input and output capacitors, offering high DC and AC impedance, a feature that allows operation in intrinsically safe applications. The SET pin features 1% initial accuracy and low temperature coefficient. Current regulation is better than 10 ppm/V from 1.5 V to 40 V.

The LT3092 can operate in a 2-terminal current source configuration in series with signal lines. Internal protection circuitry includes reverse-battery and reverse-current protection, current limiting, and thermal limiting. The LT3092 is offered in 8-lead TSOT-23, 3-lead SOT-223, and 8-lead 3 mm x 3 mm DFN packages. The LT3092 is ideal for driving sensors, remote supplies, and as a precision current limiter for local supplies.
