Datadheet AD is a complete monolithic logarithmic amplifier. Two ADs wd640 cascade can provide up to 95 dB of dynamic range at reduced bandwidth. The AD uses a successive detection scheme to provide an output current proportional to the logarithm of the input voltage. Each stage has an associated full-wave detector, whose output current depends on the absolute value of its input voltage.

On chip resistors can be used to convert this output current to a voltage with several convenient slope options. Scaling is also guaranteed for sinusoidal inputs. At least one model within this product family datawheet in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.

It is the most comprehensive PLL Synthesizer design and simulation tool available today.

Simulations performed include all key non-linear effects that are significant in affecting PLL performance. ADIsimPLL removes at least one iteration from the design process, thereby speeding the design- to-market. Cascaded gain, noise, distortion and power consumption can be calculated, plotted and exported for datashret chains with up to 50 stages. ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability.

We achieve this by incorporating datasueet and reliability checks in every scope of product and process design, and in the manufacturing process as well. International prices may differ due to local duties, taxes, fees and exchange rates. For volume-specific price or delivery quotes, please contact your local Analog Devices, Inc.

Wd640 power operation typically mW at 65 V Low cost plastic packages also available. Product Details The AD av640 a complete monolithic logarithmic amplifier. Product Highlights Absolute calibration of a wideband logarithmic amplifier is unique.

The AD is a high accuracy measurement device, not simply a logarithmic building block. Advanced design results in unprecedented stability over the full military temperature range. The fully differential signal path greatly reduces the risk of instability due to inadequate power supply decoupling and shared ground connections, a serious problem with commonly used unbalanced designs.

Differential interfaces also ensure that the appropriate ground connection can be chosen for each signal port.

They further increase versatility and simplify applications. The dc-coupled signal path eliminates the need for numerous interstage coupling capacitors and simplifies logarithmic datashset of subsonic signals. The dynamic range using cascaded ADs can be extended to 95 dB by the inclusion of a simple filter between the two devices.
