Operation beyond the maximum operating conditions for extended periods may affect product reliability. The voltage gain can be set from unity to 26 dB using a single external gain resistor. Configured such that switch W1 disables the device when Pin 1 is set to ground.
Pin Function Descriptions Pin No. For volume-specific price af8351 delivery quotes, please contact your local Analog Devices, Inc.
Select the purchase button to display inventory availability and online purchase options. The resistor RF is required to balance the output voltages required for second-order cancellation by the AD and can be selected using a chart see the SingleEnded-to-Differential Operation section.
The input and dagasheet impedances and reflection coefficients are provided in Figure 22, Figure 23, Figure 24, and Figure Pricing displayed for Evaluation Boards and Kits is based on 1-piece pricing. For additional information on reactive matching to differential sources and loads, refer to the Applications section of the AD data sheet.
This can be one of 4 stages: The exceptionally good distortion performance makes the AD an ideal solution for bit and bit IF sampling receiver designs. Trademarks and registered trademarks are the property of their respective owners. The quiescent current of the AD is 28 mA typically.

The gain can be set to any value between 0 dB and 26 dB using the resistor values specified in Figure 5, with common gain values provided in Table 4. The input signal is ac-coupled and applied to the INHI input. The AD also provides a balanced input, not provided by the balun, to the AD, which is essential for second-order cancellation.
If a model is not available for web samples, look for notes on the product page that indicate how to request samples or Contact ADI. The high impedance environment between the terminating resistors and device input pins must not have ground planes underneath or near the signal traces.
R9, R10, and R11 are provided for generic placement of matching components. To balance the outputs, an external feedback resistor, RF, is required.
Price Rohs Orders from Analog Devices. The quiescent current of the AD is 28 mA typically. EMA Antenna, Biconical, The AD may also be used to transform a single-ended signal to a differential signal.
The model has been scheduled for obsolescence, but may still be purchased for a limited time.
Low Distortion Differential RF/IF Amplifier AD8351 Data Sheet
The device ad88351 be used as a general-purpose gain block, an ADC driver, and a high speed data interface driver, among other functions. Typically decoupled dtaasheet ground using a 0. For low resistive load or source resistance, the effective Q is lower, and higher relative capacitance termination or terminations can be allowed before oscillation or excessive peaking occurs.
In some applications, baluns may be used to transform a singleended drive signal to a differential signal.
The isolation of each device when in a disabled state PWUP pin pulled low is about 60 dBc for the maximum input level of 0. Balun effects must be removed from the measurements to accurately characterize the performance of the device at frequencies exceeding 1 GHz. C4 through C7 are used to provide ac coupling.
The signal generator is bipolar, centered around ground. Connect to low impedance ground. BoxNorwood, MAU. R3 and R12 are used to ground one side of the differential drive interface for single-ended applications. It is suggested that the board be designed as shown in Figure 45 for high impedance load conditions. Please Select a Language. The power loss associated with these networks must be accounted for when attempting to measure the gain of the device. Increasing the gain of the AD increases the system noise and thus decrease the SNR but does not significantly affect the distortion.
R13 and R14 are used to ground one side of the differential output interface for single-ended applications. Evaluation Boards Pricing displayed is based on 1-piece. Following the precautions outlined in Figure 45 helps to reduce parasitic board capacitance, thus extending the bandwidth of the device and reducing potential peaking or oscillation.
The AD is designed to satisfy the demanding performance requirements datashest communications transceiver applications. The schematic and evaluation board artwork are presented in Figure 48, Figure 49, and Figure The impedance transformation is illustrated on a Smith chart xatasheet Figure Status Status indicates the current lifecycle of the product. In addition, the ground plane must be removed from under the package. Component Side Silkscreen Figure Many SAW filters are da8351 differential, allowing for a low loss output match.
