Resistor Networks, Arrays

The EXB-V4V430JV is an advanced four-channel, four-terminal resistor network. It is designed to allow rapid control of both impedance and gain of wide range of signal paths and systems. This resistor network can be used to control gain and/or impedance of both analog and digital applications.

The Four Terminals

The EXB-V4V430JV features four terminals. These terminals provide four distinct connections, two for each of the two gain and impedance angles. T1 and T2 are for the gain control terminals and T3 and T4 are for the impedance control terminals. The resistor network also contains an integrated electrical noise filter for each channel. This allows for a clean signal transmission even in noisy environments.

Resistor Network

The EXB-V4V430JV features an adjustable resistor network which provides the main function of the device. It consists of four resistors, R1, R2, and R3 and R4, that can be programmed to change the gain and/or impedance of the signal path. The resistor network is implemented in a two-dimensional array thus providing the flexibility to change either the gain or impedance independently. The resistors are all programmable via the I2C bus that connects the resistor network to the MCU.

Working Principle

The working principle of the EXB-V4V430JV is fairly simple. The resistor network is first programmed for the desired gain or impedance. This can be performed with no risk of damaging the resistor network, as it is inherently protected from high voltages and current excesses. Then, the signal is sent through the resistor network, where the gain and/or impedance settings are applied. Finally, the signal is sent to the output device, such as an amplifier or another MCU.

Applications

The EXB-V4V430JV can be used in a wide range of applications. From simple audio control and equalization to more complex signal control applications, such as radar and signal transmission, this device offers a powerful solution for any application requiring gains and/or impedances control. For low power and small size applications, the device can also be used due to its low form factor and low quiescent current.

Conclusion

The EXB-V4V430JV is an advanced four-channel, four-terminal resistor network designed for rapid control over various signal paths and systems. It features an adjustable resistor network which provides for the main function of the device. This resistor network consists of four resistors that can be programmed to produce the desired gain and/or impedance settings. With its low form factor and low quiescent current, this device is ideal for applications ranging from simple audio control and equalization to more complex signal control applications, such as radar and signal transmission.
