C4 through C7 are used to provide ac coupling. Frequently Asked Questions 1. Figure 46 illustrates the value of adding input and output series resistors to help desensitize the resonant effects of board parasitics. Operation beyond the datasheeg operating conditions for extended periods may affect product reliability.

Select the purchase button to display inventory availability and online purchase options. At least one model within this product family is in production and available for purchase. Also, please note the warehouse location for the product ordered.

For detailed drawings and chemical composition please consult our Package Site. Refer to Figure 5 when selecting gain resistor. The AD is designed to satisfy the demanding performance requirements of communications transceiver applications.

Once ad8531 order has been placed, Analog Devices, Inc. Typically decoupled to ground using a 0. The exceptionally good distortion performance makes the AD an ideal solution for bit and bit IF sampling receiver designs.

Fabricated in Analog Devices, Inc. T2 is a 1-to-1 impedance ratio balun used to transform a balanced differential signal into a single-ended signal. Calibration path provided to allow for compensation of the insertion loss of the baluns and the reactance of the coupling capacitors.

The higher the C, the smaller the R parasitic suppression resistor required.

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. The various ranges specified are as follows:. 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 common-mode output voltage level can be adjusted from 1. Not Applicable Input Interface. Biased to midsupply, typically ac-coupled. 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.

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.

Temperature Range This is the acceptable operating range of the device. Ask The Application Engineer— The unused input is ac-coupled to ground. Other models listed in the table datasheft 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. The PWUP interface can be easily driven using most standard logic interfaces.

This voltage is bypassed with a 0. Increasing the gain of the AD increases the system noise and thus decrease the SNR but does not significantly affect the distortion. Balun effects must be removed from the measurements to accurately characterize the performance of the device at frequencies exceeding 1 GHz. Output Reflection Coefficient vs.

The package for this IC i. The supply decoupling consists of a nF capacitor to ground. Please enter samples into your cart to check sample availability. The model has not been released to general production, but samples may be available. R5 and R8 can be increased to reduce gain peaking when driving from a high source impedance. Many SAW filters are inherently differential, allowing for a low loss output match.
