D Page 14 of 19 Data Sheet AD Due to package parasitic capacitance on the RG ports, high RG values datashet gain cause high ac-peaking inside the pass band, resulting in poor settling in the time domain.

Due to the inverse relationship between the gain of the device and the value of the RG resistor, any parasitic capacitance on the RG ports can result in gain-peaking at high frequencies. A Changes to Ordering Guide See the Single-Ended-to-Differential Operation section for single-ended-to-differential performance.

Once an order has been placed, Analog Devices, Inc. The various ranges specified are as follows:. Document Feedback Information furnished by Analog Devices is believed to be accurate and reliable. The AD may also be used dataseet transform a single-ended signal to a differential signal.

T1 is a 1-to-1 impedance ratio balun used to transform a single-ended input into a balanced differential signal. Evaluation Boards Pricing displayed is based on 1-piece. Trademarks and registered trademarks are the property of their respective owners.

R13 and R14 are used to ground one side of the differential output interface for single-ended applications. Biased to midsupply, typically ac-coupled.

Also, please note the warehouse location for the product ordered. Even though the differential balance is not perfect under these conditions, the distortion performance is still impressive. Please Select a Language.


Allows for monitoring or adjustment of the output common-mode voltage. The overall gain of the system is reduced by 6 dB because only half of the signal is available to the input of the SAW filter. In addition, the ground plane must be removed from under the package.

Low Distortion Differential RF/IF Amplifier AD8351 Data Sheet

Specifications subject to change without notice. Transit times from datasyeet sites may vary. Please consult the datasheet for more information. RF transmission lines connecting the input and output networks must be designed to minimize stray capacitance.

Output loading effects and noise need to be considered when using a large number of input signal paths. Configured such that switch W1 disables the device when Pin 1 is set to ground.

The PWUP interface can be easily driven using most standard logic interfaces. Pin Function Descriptions Pin No. Matching components can be calculated using datashedt Smith chart or by using a resonant approach to determine the matching network that results in a complex conjugate match. The product is appropriate for new designs but newer alternatives may exist. The ad3851 resistor values and the appropriate insertion loss and correction factors used to assess the voltage gain are shown in Table 5.

The package for this IC i. Pin Count Pin Count is qd8351 number of pins, balls, or pads on the device. One Technology Way, P. The low output noise spectral density allows for a simple implementation as depicted in Figure Fabricated in Analog Devices, Inc.

The input and output impedances and reflection coefficients are provided in Figure 22, Figure 23, Figure 24, and Figure The excellent distortion performance and wd8351 noise characteristics of this device allow for a wide range of applications. Voltage applied to this pin sets the common-mode voltage at both the input and output. Indicates the packing option of the model Tube, Reel, Tray, etc.


International prices may differ due to local duties, taxes, fees and exchange rates. The impedance transformation is illustrated on a Smith chart in Figure We achieve this by incorporating quality and reliability checks in every scope of product and process design, dqtasheet in the manufacturing process as well.

This is the date Analog Devices, Inc. Model Package Pins Temp. In addition, RIP helps to reduce low gain in-band peaking, especially for light resistive loads. Pin Count is the number of pins, balls, or pads on the device. Evaluation Board Schematic Rev. Ask The Application Engineer— The transmission line must be designed to datasheeet the appropriate characteristic impedance in the low-Z region.

In this case, R1 provides the input impedance. For additional information on reactive matching to differential sources and loads, refer to the Applications section of the AD data sheet.

The high impedance environment between the terminating resistors and device input pins must not have ground planes underneath or near the signal datahseet. The voltage gain can be datasheft from unity to 26 dB using a single external gain resistor.

The Sample button will be displayed if a model is available for web samples. The input signal is ac-coupled and applied to the INHI input.

Select the values of C1 through C4 such that their reactances are negligible at the desired frequency of operation. The AD can also be used as a single-ended-todifferential amplifier with similar distortion products as in the Rev.
