Twofunction module for ADC frontend and currentlimit signaling The analog signal is conditioned by an opamp, making it suitable for A/D conversion. In addition, the module provides a switch signal that can be preset to a currentlimit value. When the actual current reaches the preset value, the switch output transitions from low to , and the LED indicator signals the event. Key benefits Provides an ADCready analog signal path with opamp conditioning to improve conversion accuracy. Offers a programmable currentlimit trigger with a clear electrical transition (low to ) for easy integration with control logic. Includes a visual LED indicator to confirm when the current threshold is reached, enabling quick status checks. Simplifies design by combining signal conditioning and threshold monitoring in a single module. Reduces risk of overcurrent events by providing early, deterministic signaling tied to a preset limit. Function, compatibility, and performance Function: Analog signal conditioning via an opamp for A/D conversion; separate switch signal for preset currentlimit value; LED indicator for threshold notification. Compatibility: Suitable for integration with ADC frontends and currentmonitoring or protection circuits within electronic systems. Performance: The opamp conditioned analog path supports reliable ADC input; the switch output provides a discrete, binary signal when the current reaches the preset value; LED provides immediate visual feedback. Use scenarios Sensor interface for microcontroller ADC: Use the opamp conditioned signal for accurate digitization, while the switch signal and LED indicate when a predefined current level is reached in the sensor circuit. Power supply protection: Monitor load current with the preset limit; the switch output can drive a fault or warning path, and the LED provides a quick local indication of threshold crossing. Battery charging or safe charging control: Set a maximum charge current; the module signals and visualizes when the charge current hits the preset limit, enabling safe control actions. Notes The description reflects the two main functions and their behavior: analog signal conditioning by an opamp for A/D conversion, and a presettable currentlimit switch signal with LED indication when the actual current matches the preset value.
