Datasheet Maxim MAX5490 — Ficha de datos

19-3337; Rev 2; 3/05 100kΩ Precision-Matched Resistor-Divider in
SOT23
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-toend resistance of 100kΩ. Resistance ratios from 1:1 to
100:1 are available. Five standard ratios are available
(see Table 1), 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
-55В°C to +125В°C temperature range. Features
