MAX5492：10kΩ Precision-Matched Resistor-Divider in SOT23

The MAX5492 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 MAX5492 includes an extremely low-resistance-ratio temperature drift of 1.5ppm/°C (typ) over -55°C to +125°C, and has an end-to-end resistance of 10kΩ. Resistance ratios from 1:1 to 10:1 are available. Five standard ratios are available (see Table 1) in the full data sheet, and custom ratios are also available upon request. To enhance device and system robustness, the MAX5492 features ±2kV Human Body Model electrostatic discharge (ESD) protection to ensure against realworld ESD events. The MAX5492 is ideal for precision gain-setting applications where tight resistance matching and low temperature drift are necessary. The MAX5492 is available in a space-saving 5-pin SOT23 package, and is guaranteed over the military -55°C to +125°C temperature range.
