ANALOG DEVICES  LT3092ITS8#PBF

LT3092ITS8#PBF概述

    Product Introduction
    The LT3092 is a highly versatile programmable 2-terminal current source manufactured by Analog Devices. It requires only two external resistors to set the output current within a range of 0.5mA to 200mA, making it a straightforward yet powerful solution for various electronic designs. Its primary functionality lies in providing precise and regulated current sourcing capabilities, suitable for driving sensors, remote supplies, and precision current limiting applications.
    The device is compatible with a wide input voltage range (1.2V to 40V), supports high DC and AC impedance without requiring input or output capacitors, and maintains excellent temperature stability (better than 10 ppm/V). It finds extensive use in applications requiring intrinsic safety compliance, as well as in signal line current sources.
    Technical Parameters
    Below is a concise summary of key technical parameters and performance specifications of the LT3092:
    - Output Current: 0.5mA to 200mA
    - Input Voltage Range: 1.2V to 40V
    - Output Voltage Drop-Out: 1.22V to 1.65V (varies with load)
    - Line Regulation: <0.001%/V
    - Current Regulation: Better than 10ppm/V
    - Set Pin Current Accuracy: 1%
    - Temperature Coefficient: Low (<0.003%/°C)
    - Protection Features: Reverse-voltage, reverse-current, current limiting, and thermal shutdown with hysteresis.
    - Package Options: Available in SOT-223, SOT-23, and DFN packages.
    - Temperature Range:
    - Industrial (E/I grades): –40°C to 125°C
    - Automotive (MP grade): –55°C to 125°C
    - Storage Temp Range: –65°C to 150°C
    Product Features and Advantages
    The LT3092 offers several unique advantages that enhance its competitiveness and utility in a wide range of applications:
    1. Versatility: By using just two external resistors, it provides a highly flexible way to configure output currents.
    2. Stability: Excellent temperature stability and low drift over its operating temperature range make it ideal for precision applications.
    3. No External Capacitors: Stability without input or output capacitors reduces design complexity and cost.
    4. Compact Packaging: Available in small footprints like DFN and SOT-223, ideal for space-constrained designs.
    5. High Protection: Integrated reverse-voltage, reverse-current, and thermal shutdown ensure robustness and reliability.
    6. AEC-Q100 Qualified: Suitable for automotive-grade applications with stringent quality and reliability standards.
    Application Case Studies and Recommendations
    Applications:
    - Driving sensors in industrial automation systems.
    - Remote current supply in IoT and communication equipment.
    - Precision current limiting in power management subsystems.

    Use Case Example:
    Consider an industrial pressure sensor powered by the LT3092. The sensor needs a stable current of 50mA to 200mA. Selecting RSET = 20kΩ (200mV) and ROUT = 1kΩ will yield a stable output current of ~50mA, easily configurable via resistor selection. Ensure proper PCB layout with minimal parasitic capacitance to maintain optimal performance.
    Recommendations:
    - Always test the circuit's stability under actual operating conditions, especially when interfacing with long wires or high-impedance loads.
    - Consider adding series damping resistors (e.g., 5Ω–10Ω) if high-Q lines lead to instability.
    - Surface coating or guard rings may be necessary for high-humidity environments to mitigate leakage issues.
    Compatibility and Support
    The LT3092 is designed to seamlessly integrate with most common electronics and is compatible with various existing modules or interfaces. Analog Devices provides comprehensive support, including:
    - Detailed documentation and application notes.
    - Design tools and simulation models for quick prototyping.
    - Long-term availability and quality assurance for automotive and industrial-grade applications.
