See DOS device names. 105, a new precision voltage divider voltage divider: see potentiometer. . The features of the PRN105 are tight ratio tolerance, tight Temperature Coefficient The temperature coefficient is the relative change of a physical property when the temperature is changed by 1 K. In the following formula, let R be the physical property to be measured, let T be the temperature of at which the property is measured. of Resistance (TCR TCR T cell receptor. ), and a wide range of resistor values. The PRN105 offers an integrated solution in a SOT23 package which provides benefits of board space saving. This device provides a high degree of stability, low noise and the proven reliability characteristic of Tantalum tantalum (tăn`tələm) [from Tantalus], metallic chemical element; symbol Ta; at. no. 73; at. wt. 180.9479; m.p. 2,996°C;; b.p. 5,400±100°C;; sp. gr. 16.65 at 20°C;; valence +2, +3, +4, or +5. Nitride. CAMD's PRN105 is very useful for solving the voltage divider requirements for many applications with a wide range of resistor values. Some examples of the application of the precision voltage divider resistor array are gain control of operational amplifiers, setting the voltage for voltage regulators, attenuations, and a level shifter for interfacing TTL/MOS. In many applications, e.g. voltage reference or op amp gain control, it is the ratio of the two resistors that determines the reference voltage or the op amp output, not the absolute value of each resistor. CAMD's PRN105 meets this requirement by manufacturing 2 thin film resistors at the same time with the same material on the same substrate. This yields a closer tolerance of ratio matching than 2 discrete resistors of equal absolute tolerance, and better temperature tracking. The SOT23 precision voltage divider is also available in custom values and configurations. Pricing for PRN105 in 100K quantities is $0.19. Samples are available upon request. Production lead-time is 8 weeks ARO.
