In today's pursuit of ultimate efficiency and reliability in electronic systems, high-precision current sensing has become essential across industrial automation, automotive electronics, and renewable energy sectors. Accurate current dynamics monitoring is pivotal for ensuring system stability and performance. The MSA2293 ultra-precision current sense amplifier emerges as a breakthrough solution, setting new industry benchmarks with its revolutionary capabilities!

Performance Breakthrough: Four Core Advantages

  1. Unshakable Stability Across Wide Voltage Range:

    Operates stably within a broad common-mode voltage range of -4V to +90V while withstanding voltages from -30V to 100V. This versatility enables seamless performance in complex circuit environments, particularly excelling in handling inductive kickback.

  2. Precision Redefined, Accuracy Perfected:

    Offset Voltage: 150µV (Typ. @ 20V/V)

    Drift Control: ±0.2µV/°C (Offset), ±1.8ppm/°C (Gain)

    Gain Error: 0.2% (Typical)

    CMRR: 160dB (DC), delivering lab-grade precision for demanding applications.

  3. Ultrafast Response for Critical Safety:

    With 1.1MHz bandwidth and 2.5V/µs slew rate, the MSA2293 accurately measures DC currents while enabling instant response in high-speed scenarios like rapid overcurrent protection, safeguarding system security.

  4. Flexible Gains for Universal Coverage:

    Three configurable gains (20V/V, 50V/V, 100V/V) adapt to diverse current sensing needs, significantly expanding application scenarios.
