The JAN1N4984US is a precision analog signal monitoring IC designed for a wide range of applications. It is a single-channel, two-pole, impedance matching, active bridge, and frequency-dependent amplifier. The device is ideal for monitoring the signal from a low-voltage analog transceiver, whose output may vary significantly from application to application. The device provides a DC output voltage signal proportional to its input voltage, which is then amplified and provided as an output voltage signal.

The JAN1N4984US is suitable for applications in automotive, medical, and consumer circuitry monitoring. It is available in sample and final production form and uses a low-power supply and low-cost packages. Its design is temperature compensated and requires no external components for proper signal conditioning.

The JAN1N4984US operates at an adjustable supply voltage from 1.8V to 15V. Operating beyond the supply voltage may damage the device. At the same time, it also has high impedance for input signals up to 200V DC, which requires a low-voltage amplifier with suitable input protection. It has a wide common-mode input range of -35V to 200V, and allows input signals to be monitored in both ac and dc conditions.

The JAN1N4984US amplifies AC signals to an adjustable gain of up to 74dBm and, depending on the external components used, provides a frequency response of up to 10MHz. For higher frequency applications, additional external capacitors must be used. The wideband, low noise and linear response of the JAN1N4984US make it suitable for wideband RF measurements and signal filtering applications.

In addition, the device has an on-board adjustable low-pass filter (LPF) and band-pass filter (BPF) that can be used to provide additional frequency-dependent response. The LPF performs the function of reducing unwanted low-frequency signals, while the BPF is used to restrict the frequency range of the output. These features make the device suitable for applications requiring high-frequency signal processing or monitoring.

The JAN1N4984US is a versatile and easy to use device with features that make it suitable for a variety of applications. It is also a cost-effective solution for high-precision signal processing and monitoring required in automotive, medical, and consumer circuitry. Its flexible design makes it suitable for a range of signal-processing applications, while its high-impedance input makes it well suited for applications requiring an isolated power source.
