The is a 100Kohm precision-matched resistor-divider in 3 pin SOT-23 package. This precision resistor divider consists of two accurately matched resistors with access to ends and centre of divider. The device provides an extremely low resistance-ratio temperature drift of 1ppm/°C typ over -55°C to +125°C and has an end to end resistance of 100Kohm. It is ideal for precision gain-setting applications where tight resistance matching and low temperature drift are necessary. It is used in base stations, instrumentation, automatic test equipment and precision gain setting.
