General Description

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), and custom ratios are also available upon request. To enhance device and system robustness, the MAX5492 features ±2kV Human Body Model electrostat ic discharge (ESD) protection to ensure against real world ESD events. The MAX5492 is ideal for precision gain-setting applications where tight resistance matching and low temperature drift are necessary.
