MAX5491RA02500+T by Analog Devices

Precision-Matched Resistor-Divider in SOT23


The MAX5491 precision resistor-divider consists of two accurately matched resistors with access to the ends and center of the divider. This device offers excellent resistance matching of 0.035% (A grade), 0.05% (B grade), and 0.1% (C grade). The MAX5491 includes an extremely low resistance-ratio temperature drift of 2ppm/°C over -40°C to +85°C, and has an end-to-end resistance of 30kΩ. Resistance ratios from 1:1 to 30:1 are available. Ten standard ratios are available (see Table 1), and custom ratios are also available upon request. To enhance device and system robustness, the MAX5491 also features ±2kV Human Body Model electrostatic discharge (ESD) protection to ensure against real-world ESD events. The MAX5491 is ideal for precision gain-setting applications where tight resistance matching and low temperature drift are necessary. The MAX5491 is available in a space-saving 3-pin SOT23 package, and is guaranteed over the extended -40°C to +85°C temperature range.
