MAX5491RA02500+T

MAX5491 is a precision-matched resistor-divider. It consists of two accurately matched resistors with access to the ends and centre of the divider. This device offers excellent resistance matching of 0.035% (A grade). To enhance device and system robustness, it also features ±2KV human body Model electrostatic discharge (ESD) protection to ensure against real-world ESD events. It is ideal for precision gain-setting applications where tight resistance matching and low temperature drift are necessary. Application includes industrial process control, instrumentation, precision gain setting, medical equipment, automatic test equipment, base stations.
