amplifier that uses very high speed complementary technology to provide a bandwidth of up to 410 MHz while drawing only
4.1 mA of quiescent current. With a slew rate of 940 V/µs and an output stage optimized for driving a standard 100 Ω load, this circuit is highly suitable for applications where speed and power­saving are the main requirements. The device is a single operator available in a Flat-8 hermetic ceramic package, saving board space as well as providing excellent thermal and dynamic performance.

3. The magnitude of input and output voltage must never exceed VCC +0.3 V.
4. Short-circuits can cause excessive heating. Destructive dissipation can result from short-circuits on all amplifiers.
5. Human body model: a 100 pF capacitor is charged to the specified voltage, then discharged through a
1.5 kΩ resistor between two pins of the device. This is done for all couples of connected pin combinations while the other pins are floating.
6. This is a minimum value. Machine model: a 200 pF capacitor is charged to the specified voltage, then discharged directly between two pins of the device with no external series resistor (internal resistor < 5 Ω). This is done for all couples of connected pin combinations while the other pins are floating.

Power supply considerations RHF350

3 Power supply considerations

Correct power supply bypassing is very important to optimize performance in high­frequency ranges. The bypass capacitors should be placed as close as possible to the IC pins to improve high-frequency bypassing. A capacitor greater than 1 minimize the distortion. For better quality bypassing, a 10 nF capacitor can be added. It should also be placed as close as possible to the IC pins. The bypass capacitors must be incorporated for both the negative and positive supply.

In the event that a single supply system is used, biasing is necessary to obtain a positive output dynamic range between the 0 V and +V
and VOL, the amplifier provides an output swing from +0.9 V to +4.1 V on a 100 Ω load.

The amplifier must be biased with a mid-supply (nominally +V DC component of the signal at this value. Several options are possible to provide this bias supply, such as a virtual ground using an operational amplifier or a two-resistance divider (which is the cheapest solution). A high resistance value is required to limit the current consumption. On the other hand, the current must be high enough to bias the non-inverting input of the amplifier. If we consider this bias current (35 through the resistance divider, to keep a stable mid-supply two resistances of 750 used.

On a 1 Hz bandwidth the thermal noise is reduced to:

where k is the Boltzmann's constant, equal to 1,374.E(-23)J/°K. T is the temperature (°K).
The output noise eNo is calculated using the superposition theorem. However, eNo is not the simple sum of all noise sources, but rather the square root of the sum of the square of each noise source, as shown in

To measure the negative input current noise iNn, we set R3=0 and use Equation 5. This time, the gain must be lower in order to decrease the thermal noise contribution.
R3=0, gain: g=10

4.3 Measurement of the positive input current noise iNp

To extract iNp from Equation 3, a resistance R3 is connected to the non-inverting input. The value of R3 must be chosen in order to keep its thermal noise contribution as low as possible against the iNp contribution.

A one-frequency (one-tone) input signal contributes to harmonic distortion. A two-tone input signal contributes to harmonic distortion and to the intermodulation product.
The study of the intermodulation and distortion for a two-tone input signal is the first step in characterizing the driving capability of multi-tone input signals.

RHF350 Inverting amplifier biasing

6 Inverting amplifier biasing

A resistance is necessary to achieve good input biasing, such as resistance R shown in
Figure 28.
The value of this resistance is calculated from the negative and positive input bias current. The aim is to compensate for the offset bias current, which can affect the input offset voltage and the output DC component. Assuming I R is:

From the resistors Rfb and RG we can directly calculate the gain of the filter in a classic non­inverting amplification configuration.

The cut-off frequency is not gain-dependent and so becomes:
The damping factor is calculated by the following expression.

The higher the gain, the more sensitive the damping factor is. When the gain is higher than 1, it is preferable to use very stable resistor and capacitor values. In the case of R1=R2=R:
Due to a limited selection of capacitor values in comparison with resistor values, we can set
