MAX5490VC10000+T Overview
Manufactured by maxim integrated, this device is designed to provide a precise, low temperature coefficient voltage division in applications such as instrumentation, communication equipment, and industrial control systems. The MAX5490VC10000+T offers excellent matching between the two resistors, ensuring accurate voltage division and minimal error. Additionally, it has a wide operating voltage range and can operate reliably over a wide temperature range.
MAX5490VC10000+T Description
The MAX5490 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 MAX5490 provides an extremely low resistance-ratio temperature drift of 1ppm/°C (typ) over -55°C to +125°C, and has an end-toend resistance of 100kΩ. Resistance ratios from 1:1 to 100:1 are available. Five standard ratios are available (see Table 1), and custom ratios are also available upon request. The MAX5490 is ideal for precision gain-setting applications where tight resistance matching and low temperature drift are necessary.
The MAX5490 is available in a space-saving 3-pin SOT23 package, and is guaranteed over the military -55°C to +125°C temperature range.

MAX5490VC10000+T Details
The MAX5490 consists of two precision, low-ratio-drift resistors with an end-toend resistance of 100kΩ (R1 + R2). P3 is the set point of the divider. The maximum working voltage of the MAX5490 is 80V. This device offers a wide range of resistance ratios (R1/R2) from 1:1 to 100:1 and is ideal for precision operational amplifier gain/attenuation control. A maximum initial ratio accuracy of 0.035% and a low 1ppm/°C ratio drift enhance system accuracy.
