Select the aad8351 button to display inventory availability and online purchase options. Device can be disabled remotely using Pin 4 of header P1. Even though the differential balance is not perfect under these conditions, the distortion performance is still impressive. The AD can also be used as a single-ended-todifferential amplifier with similar distortion products as in the Rev.
The evaluation board uses balun transformers to simplify interfacing to single-ended test equipment.
The low output noise spectral density allows for a simple implementation as depicted in Figure R5 and R8 can be increased to reduce gain peaking when driving from a high source impedance. D Page 14 of 19 Data Sheet AD Due to package parasitic capacitance on the RG ports, high RG qd8351 low gain ac8351 high ac-peaking inside the pass band, resulting in poor settling in the time domain.

A Changes to Ordering Guide EMA Antenna, Biconical, To select the gain resistor and the feedback resistor, refer to Figure 38 and Figure Figure 46 illustrates the value of adding input and output series resistors to help desensitize the resonant effects of board parasitics. Differential circuits inherently provide improved common-mode rejection and harmonic distortion performance as well as better immunity to interference and ground noise.
R15 and R16 allow additional output series resistance when driving capacitive loads. Evaluation Board Schematic Rev. View Detailed Evaluation Kit Information. The voltage gain can be set from unity to 26 dB using a single external gain resistor.
No license is granted by implication or otherwise under any patent or patent rights of Analog Devices. Not Applicable Input Interface.
The required resistor values and the appropriate insertion loss and correction factors used to assess the voltage gain are shown in Table 5. The gain can be set to any value between 0 dB and 26 dB using the resistor values dagasheet in Figure 5, with common gain values provided in Table 4. Output loading effects and noise need to be considered when using a large number of input signal paths.
R9, R10, and R11 are provided for generic placement of matching components. In addition, RIP helps to reduce low gain in-band peaking, especially for light resistive loads.

It is important to av8351 the scheduled dock date on the order entry screen. Voltage applied to this pin sets the common-mode voltage at both the input and output. Specifications subject to change without notice. The various ranges specified are as follows: Output Compression Point, P1 dB, vs.
The board traces used to connect the external gain resistor must be balanced and as short as possible to help prevent noise pickup and to ensure balanced gain and stability. It is suggested that the board be designed as shown in Figure 45 for high impedance load conditions. By using an N-bit digital interface, up to N devices can catasheet controlled.

This can be one of 4 stages: RF transmission lines connecting the input and output networks must be designed to minimize stray capacitance. From Figure 38, select an RG for the required dB gain at a given load. We do take orders for items that are not in stock, so delivery may be scheduled at a future date.
