The MAX5490 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 MAX5490 provides an extremely low resistance-ratio temperature drift of 1ppm/°C (typ) over -55°C to +125°C, and has an end-to-end resistance of 100kΩ. Resistance ratios from 1:1 to 100:1 are available. Five standard ratios are available (see Table 1 in the full data sheet), and custom ratios are also available upon request. The MAX5490 is ideal for precision gain-setting applications where tight resistance matching and low temperature drift are necessary.

The MAX5490 is available in a space-saving 3-pin SOT23 package, and is guaranteed over the military -55°C to +125°C temperature range.
