Pin Description
Detailed Description
As shown in the Block Diagram, the MAX5491 consists
of two precision, low-ratio-drift resistors with an end-to-
end resistance of 30kΩ (R1 + R2). P3 is the center tap
of the divider. The maximum working voltage of the
MAX5491 is 50V. This device offers a wide range of
resistance ratios (R1/R2) from 1:1 to 30:1 and is ideally
suited for precision operational amplifier gain/attenua-
tion control. The MAX5491 features a ±2kV ESD protec-
tion that enhances system robustness. A maximum
initial ratio accuracy of 0.035% and a low 2ppm/°C ratio
drift enhance system accuracy.
