Additional Details

The TS391AG-AF5-R operates with a single supply voltage, and its low input bias current and input offset voltage contribute to its accuracy. An external pull-up resistor is required on the open-collector output to define the high-level output voltage. It's essential to consult the datasheet for the exact supply voltage range, input bias current, input offset voltage, response time, operating temperature range, and package details (e.g., SOT-23). This voltage comparator is a cost-effective and reliable solution for a variety of voltage comparison applications where low power consumption is a key requirement.
