Resistor Networks, Arrays are formed by connecting several resistors together as either a parallel or series arrangement for the purpose of amplifying a signal or obtaining an adjustable resistance and voltage across a devices terminals. The resistors are organised in such a way it will uniformly divide a voltage across its terminals. The 4607X-101-153LF Resistor Networks, Arrays are a good example of this and worthy of closer look into their application field and working principle.

Application Field

The 4607X-101-153LF Resistor Networks, Arrays are an 8-pin integrated circuit (IC) package with a divide-by-4 to 10-bit binary spread divisor. The design of this resistor network is such that it only requires one external resistor to set the dividing capabilities, which allows these identical networks to be used in multiple divided systems. The 4607X-101-153LF can be used to divide voltage ratios from 4 to 10,000. This programma ble network also includes an automatic stabilizing resistor that compensates the output voltage for temperature and tolerances. As such, this makes it perfect for use in protection circuits, power supplies, signal processors and similar circuits.

Working Principle

The 4607X-101-153LF Resistor Networks, Arrays work based on a binary method, referred to as \'binning\'. This kind of system divides a voltage in exact whole-number subdivisions only. For instance, when dividing 8 volts, it would be divided in exactly 8 parts, each with a 1-volt output. In order to divide the voltage, the IC considers every bit to be the ‘on’ or ‘off’ switching state of the resistors which generate the various divisions. The resistors are arranged in a series between two voltage sources. Depending on the data value of each bit, the resistive pathway from the positive to the negative side is blocked or opened. In this way, the voltage from the positive side is divided up in accordance with the bits.

The 4607X-101-153LF Resistor Networks, Arrays achieve such precise dividers through a clever combination of resistors and switches. The switches are all connected in parallel and act as a kind of ‘short circuit’, the purpose of which is to reduce the overall resistance of the circuit. By bringing resistances in parallel, their overall resistance will be lowered – this is how the divider works. The 4607X-101-153LF ‘binary spread’ network also uses the same kind of paralleled resistance approach, but instead of a single resistor per bit, two resistors are used to generate the voltage subdivisions.

The 4607X-101-153LF Resistor Networks, Arrays are adjustable using an external ‘stabilizing’ resistor. This resistor can be adjusted to compensate the output voltage for temperature and tolerances. The adjustability also means that the exact validity of the division can be checked and adjusted during installation and usage. Furthermore, the size of the resistor network allows it to be conveniently used in a variety of systems.

In summary, the 4607X-101-153LF Resistor Networks, Arrays are a good example of voltage dividers due to their small size, adjustable resistances and high precisions. They are suitable for use in protection circuits, power supplies, signal processors and similar circuits. Due to their being binary spread networks, the binary method thus allowing them to dexterously divide the voltage in exact subdivisions.
