The device can be used as a general-purpose gain block, an ADC driver, and a high speed data interface driver, among other functions. Input Reflection Coefficient vs. As the load increases due to the addition of N devices, the distortion performance will degrade due to the heavier loading.

Low Distortion Differential RF/IF Amplifier AD8351 Data Sheet

In sd8351 applications, the input of the AD is terminated to a lower impedance to provide an impedance match to the driving source, as shown in Figure The voltage gain datsaheet be set from unity to 26 dB using a single external gain resistor. This voltage is bypassed with a 0.

The low output noise spectral density allows for a simple implementation as depicted in Figure Other models listed in the table may still be available if they have a status that is not obsolete.

No license is granted by implication or otherwise under any patent or patent rights of Analog Devices. This is the acceptable operating range of the device. BoxNorwood, MAU. The datashete ranges specified are as follows: Transit times from these sites may vary.

However, no responsibility is assumed by Analog Devices for its use, nor for any infringements of patents or other rights of third parties that may result from its use. The input and output impedances and reflection coefficients are provided in Figure 22, Figure 23, Figure 24, and Figure Please consult the datasheet for more information.


Model The model number is a specific version of datashheet generic that can be purchased or sampled. R13 and R14 are used to ground one side of the differential output interface for single-ended applications. Resources AD Gerber Files. In addition, the ground plane must be removed from under the package. Typically decoupled to ground using a 0. Ask The Application Engineer— It is important to note the scheduled dock date on the order entry screen.

Sample availability may be better than production availability. Evaluation Board Schematic Rev.

For volume-specific price or delivery quotes, please contact your local Analog Devices, Inc. International prices may vary due to local duties, taxes, fees and exchange rates. From Figure 38, select an RG for the required dB gain at a given load.

The evaluation board integrates bypassable transformers to allow single ended or differential inputs and output, place holders for an impedance matching network and the evaluation board requires only a single supply within the range of 3.

Please Select a Region. RL is the single-ended load resistance. Product Lifecycle Production At least one model within this product family is in production and available for purchase.

Differential circuits inherently provide improved common-mode rejection and harmonic distortion performance as well as better immunity to interference and ground noise.

Third-Order Intermodulation Distortion vs. Please enter samples into your cart to check sample availability. This AD circuit then provides the gain, isolation, and source matching for the AD R15 and R16 allow additional output series resistance when driving capacitive loads. Even though the differential balance is not perfect under these conditions, the distortion performance is still impressive.


Small ae8351 suppressing resistors may be necessary at the device input pins to help desensitize de-Q the resonant effects of the device bond wires and surrounding parasitic board capacitance.

The quiescent current of the AD is 28 mA typically. Fabricated in Analog Devices, Inc. We do take orders for items that are not in fatasheet, so delivery may be scheduled at a future date. Typically decoupled to ground with a 0. The power loss associated with these networks must be accounted for when attempting to measure the gain of the device. Balun effects must datsaheet removed from the measurements to accurately characterize the performance of the device at frequencies exceeding 1 GHz.

The exceptionally good distortion performance makes the AD an ideal solution for bit and bit IF sampling receiver designs.

Low Distortion Differential RF/IF Amplifier AD Data Sheet

For optimum performance, ad88351 AD and the AD are driven differentially. Pin Function Descriptions Pin No. Not Applicable Input Interface. To balance the outputs, an external feedback resistor, RF, is required. The high impedance environment between the terminating resistors and device input pins must adtasheet have ground planes underneath or near the signal traces. The model is currently being produced, and generally available for purchase and sampling.

Voltage applied to this pin sets the common-mode voltage at both the input and output.
