.. 19-3695; Rev 0; 5/05 10kΩ Precision-Matched Resistor-Divider in SOT23 MAX5492 General Description The MAX5492 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 MAX5492 includes an extremely low-resistance-ratio temperature drift of 1.5ppm/°C (typ) over -55°C to +125°C, and has an endto-end resistance of 10kΩ. Resistance ratios from 1:1 to 10:1 are available. Five standard ratios are available (see Table 1), and custom ratios are also available upon request. To enhance device and system robustness, the MAX5492 Features ±2k V Human Body Model electrostatic discharge (ESD) protection to ensure against realworld ESD events. The MAX5492 is ideal for precision gain-setting applications where tight resistance matching and low temperature drift are necessary. The MAX5492 is available in a space-saving 5-pin SOT23 package, and is guaranteed over the military -55°C to +125°C temperature range. - Resistance Ratios from 1:1 to 10:1 - Custom Ratios Available Upon Request - Tight Initial Ratio Accuracy 0.035% (MAX5492A) 0.05% (MAX5492B) 0.1% (MAX5492C) - Low 1.5ppm/°C (typ) Resistor-Ratio-Drift (1.1:1) - Up to 40V Operating Voltage Across Sum of R1 and R2 - Tiny 5-Pin SOT23 Package Features Applications Industrial Process Control Instrumentation Precision Gain Setting Medical Equipment Automatic Test Equipment Base Stations PART Ordering Information- TEMP RANGE RATIO PINACCURACY PACKAGE (%) 0.035 0.05 0.1 MAX5492_A_ _ _ _ _ -T -55°C to +125°C 5 SOT23-5 MAX5492_B_ _ _ _ _ -T -55°C to +125°C 5 SOT23-5 MAX5492_C_ _ _ _ _ -T -55°C to +125°C 5 SOT23-5 - See the How to Order section for more details.
