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.
