California Micro Devices' (CAMD), thin film voltage divider resistor array in SOT23 package, the PRN105 features tight ratio tolerance, tight temperature coefficient of resistance (TCR), 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 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, eg 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. The PRN105 meets this requirement by manufacturing two thin film resistors at the same time with the same material on the same substrate. This yields a closer tolerance of ratio matching than two discrete resistors of equal absolute tolerance, and better temperature tracking.
The SOT23 precision voltage divider is also available in custom values and configurations.
