PRODUCT OVERVIEW

What Is the LT3092IDD#TRPBF?

LT3092IDD#TRPBF is a programmable 2-terminal current source from Analog Devices (formerly Linear Technology). 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 LT3092IDD#TRPBF is stable without input and output capacitors, offering high DC and AC impedance. This feature allows operation in intrinsically safe applications. The SET pin features 1% initial accuracy and low temperature coefficient. Current regulation is better than 10ppm/V from 1.5V to 40V.

The device can operate in a 2-terminal current source configuration in series with signal lines. It is ideal for driving sensors, remote supplies, and as a precision current limiter for local supplies. Internal protection circuitry includes reverse-battery and reverse-current protection, current limiting and thermal limiting. The LT3092IDD#TRPBF is offered in an 8-lead DFN (3mm × 3mm) package and is rated for operation from –40°C to +125°C as an I-Grade device.

Circuit Considerations for LT3092IDD#TRPBF

Output Current Programming

The LT3092IDD#TRPBF output current is set with two external resistors:

Output Current Formula: I_OUT = 10µA × (R_SET / R_OUT)
Current Range: 0.5mA to 200mA
SET Pin Current: 100µA with 1% initial accuracy
Resistor Ratio: The resistor ratio sets the output current, providing flexibility for various applications

PCB and Power-Supply Guidance

Current source performance depends on layout and component selection:

Input/Output Capacitors: Not required for stability, offering high DC and AC impedance
Exposed Pad Connection: The exposed pad (Pin 9) is connected to OUT and must be soldered to the PCB
2-Terminal Operation: Can operate in series with signal lines as a floating current source
Protection Features: Built-in reverse-battery and reverse-current protection, current limiting, and thermal limiting ensure robust operation
PCB Layout: Keep resistor traces short and close to the device for accurate current setting
Thermal Management: θJA = 28°C/W for the DFN package; ensure adequate copper area for heat dissipation
Verify the recommended PCB footprint from the official datasheet before production
