... The conve- nient power-on reset (POR) sets the wiper to midscale position at power-up and the easy-to-use up/down interface allows glitchless switching between resistor taps. Six inputs control the 14-pin MAX5451/ MAX5453/MAX5455 potentiometers. Four inputs control the 10-pin MAX5450/MAX5452/MAX5454 variable resis- tors. ...

... Figure 6a shows the MAX5450/MAX5452/MAX5454 variable resistor in series with a resistor to ground to form the adjustable gain control. Figure 6b shows the MAX5451/MAX5453/ MAX5455 as a 3-terminal potentiometer. In these appli- cations the low 5ppm/°C ratiometric tempco allows for a very stable adjustable gain over temperature. ...
