FUNCTION
R1 Connection Terminal
Sense Connection for Low Side of Resistor String. Leave floating or connect in a Kelvin connection
configuration.
R2 Connection Terminal
Set-Point Connection Terminal
Sense Connection for High Side of Resistor String. Leave floating or connect in a Kelvin connection
configuration.
Detailed Description
The MAX5492 consists of two precision, low-ratio-drift
resistors with an end-to-end resistance of 10k ? (R 1 + R 2 ).
(See Figure 1.) P3 is the set point of the divider. The
maximum working voltage of the MAX5492 is 40V.
This device offers a wide range of resistance ratios
(R 1 /R 2 ) from 1:1 to 10:1 and is ideally suited for preci-
sion operational-amplifier gain/attenuation control. The
MAX5492 features a ±2kV ESD protection that
enhances system robustness. A maximum initial ratio
accuracy of 0.035% and a low ratio drift enhance sys-
tem accuracy.
Applications Information
Kelvin Sensing
Kelvin sensing can improve accuracy in sensitive appli-
cations. Apply a voltage or current at P1 and use sense
high (SH) and sense low (SL) to monitor the voltage at
the upper and lower ends of the resistor string.
