DESCRIPTION

· The MAX5491 is a precision resistor-divider with two accurately matched resistors, offering access to the ends and center of the divider.

· It provides excellent resistance matching with grades of 0.035% (A grade), 0.05% (B grade), and 0.1% (C grade).

· Features an extremely low resistance-ratio temperature drift of 2ppm/°C over -40°C to +85°C and an end-to-end resistance of 30k Ω.

· Available in resistance ratios from 1:1 to 30:1, with ten standard ratios and custom ratios upon request.

· Includes ±2kV Human Body Model ESD protection for enhanced device and system robustness.

· Ideal for precision gain-setting applications requiring tight resistance matching and low temperature drift.

· Available in a space-saving 3-pin SOT23 package, guaranteed over the extended -40°C to +85°C temperature range.
