10k ? Precision-Matched
Resistor-Divider in SOT23
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 10k ? . 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.
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.
