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

e xtre me ly low re s is ta nc e -ra tio te mp e ra ture d rift of

1ppm/°C (typ) over -40°C to +85°C, and has an end-to-

end 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.

♦ Resistance Ratios from 1:1 to 100:1

♦ Custom Ratios Available Upon Request

♦ Tight Initial Ratio Accuracy

♦ Low 1ppm/°C (typ) Resistor-Ratio-Drift

♦ Up to 80V Operating Voltage Across Sum of R1

and R2

♦ Tiny 3-Pin SOT23 Package

The MAX5490 is a va ila b le in a s p a c e -s a ving 3-p in

SOT23 package, and is guaranteed over the extended

-40°C to +85°C temperature range.
