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 30k
(R
1
+ R
2
). 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 (R
1
/R
2
) 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.
