100kΩ Precision-Matched Resistor-Divider in SOT23 MAX5490
General Description
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 -40°C to +85°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 extended -40°C to +85°C temperature range. ♦ Resistance Ratios from 1:1 to 100:1 ♦ Custom Ratios Available Upon Request ♦ Tight Initial Ratio Accuracy 0.035% (MAX5490A) 0.05% (MAX5490B) 0.1% (MAX5490C) ♦ Low 1ppm/°C (typ) Resistor-Ratio-Drift ♦ Up to 80V Operating Voltage Across Sum of R1 and R2 ♦ Tiny 3-Pin SOT23 Package
