MNR34J5ABJ562

Resistor Networks, Arrays

The MNR34J5ABJ562 is a resistor network arrangement of discrete resistors configured into an array. Resistor networks, also referred to as resistor arrays, provide good signal isolation between the input and output, while providing low cost and small size solution to multiple resistor networks. The MNR34J5ABJ562 is typically used in monitoring, ADC (analog to digital converter) and signal conditioning applications.

General Features

The MNR34J5ABJ562 is a four resistor network configured in a single in-line package. The device has a nominal resistance tolerance of 5% and is rated for 2.5W at 25°C. Operating temperature range is -55°C to +125°C. The network has an operating voltage of up to 75V. The resistors may be ordered with 100Ω, 150Ω and 200Ω nominal values.

Working Principle

The MNR34J5ABJ562 has two distinct operations. The first operation is as a four-resistive network, with each resistive path connecting a pair of input and/or output contacts. For this reason, the network is referred to as a ‘mixed-mode network’. The second, and main, operation is as an attenuator or voltage divider. When configured as such, the resistor network acts as a voltage divider, which divides an applied voltage by a specific ratio in order to produce an equivalent output voltage.

The maximum resistance between each pair of contacts on the MNR34J5ABJ562 is determined by a nominal value, typically either 100Ω, 150Ω or 200Ω. This value determines the total resistance of the network in series mode and also determines the attenuation ratio when configured as a voltage divider. As such, by varying these nominal values it is possible to configure the device for a range of attenuation ratios.

By combining the resistor network with a gate voltage (or multiple gate voltages) and suitable control circuitry, it is possible to form a voltage-controlled resistor network attenuator. This type of attenuator can be operated in a linear or non-linear mode, depending on the level of control required.

Application Field

MNR34J5ABJ562 is used in wide range of applications, including the control of audio and video signals in consumer electronics, medical testing and instrumentation, automotive electronics, and process control. The MNR34J5ABJ562 is also suitable for use as a voltage divider for powering logic circuits, in order to prevent over-powering of the logic circuit by the higher voltage. Voltage dividers may also be used to convert AC voltages to lower levels where a linear scaling of voltage levels is required, for example in the control of lighting circuits. The MNR34J5ABJ562 is also suitable for use in power dissipation systems in power management systems, and in automotive control systems.

Conclusion

The MNR34J5ABJ562 is a four resistor network configured in a single in-line package. It is used in applications such as audio/video signal control, medical testing and instrumentation, automotive control, process control, voltage conversion, power dissipation and power management. The resistor network is configured as a voltage divider with varying resistance values to provide a variety of attenuation ratios. It can also be combined with a gate voltage and suitable control circuitry to form a voltage-controlled resistor network attenuator.
