MAX5490, MAX5491, MAX5492
The MAX5490 family of precision resistor-dividers consists of two accurately
matched resistors with access to the ends and center of the divider. This family
oers excellent resistance matching of 0.035% (A grade), 0.05% (B grade), and
0.1% (C grade); 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 30k.
Resistance ratios from 1:1 to 30:1 are available, as are 10 standard ratios.
Benefits
