Description

AD641AP Overview
The linear amplifier is packaged in a 20-LCC (J-Lead) case. This is a Logarithmic type op amp. Linear amplifier is delivered in a Tube case. The number of terminations approaches 20. Buffer amplifier has a total of 20 pins. Please take in mind that this instrumentation amplifier should be run at 5V. To be specific, this instrumentation amplifier is a type of Analog Computational Functions. The buffer op amp includes 20 pins. Regarding input offset voltage, op amp rates 50μV. Surface Mount is the recommended mounting type for this linear amplifier. With regard to operating temperature, this op amp functions well at -40°C~85°C. This op amp can operate from a supply current at 44mA. This linear amplifier has a total of 1 elements. Buffer amplifier has a quiescent current of 35mA. Instrumentation amplifier resistance should remain within the range of 500kOhm. The other type of analog IC used in this op amp ic is known as LOG OR ANTILOG AMPLIFIER.

The AD641 is a 250 MHz, demodulating logarithmic amplifier with an accuracy of ±2.0 dB and 44 dB dynamic range. The AD641 uses a successive detection architecture to provide an output current that is logarithmically proportional to its input voltage. The output current can be converted to a voltage using one of several on-chip resistors to select the slope. A single AD641 provides up to 44 dB of dynamic range at speeds up to 250 MHz, and two cascaded AD641s together can provide 58 dB of dynamic range at speeds up to 250 MHz. The AD641 is fully stable and well characterized over either the industrial or military temperature ranges. The AD641 is not a logarithmic building block, but rather a complete logarithmic solution for compressing and measuring wide dynamic range signals. The AD641 is comprised of five stages and each stage has a full wave rectifier, whose current depends on the absolute value of its input voltage. The output of these stages are summed together to provide the demodulated output current scaled at 1 mA per decade (50 µA/dB). Without utilizing the 10× input attenuator, log conformance of 2.0 dB is maintained over the input range –44 dBm to 0 dBm. The attenuator offers the most flexibility without significantly impacting performance. The 250 MHz bandwidth and temperature stability make this product ideal for high speed signal power measurement in RF/ IF systems. ECM/Radar and Communication applications are routinely in the 100 MHz–180 MHz range for power measurement. The bandwidth and accuracy, as well as dynamic range, make this part ideal for high speed, wide dynamic range signals. The AD641 is offered in industrial (–40°C to 85°C) and military (–55°C to 125°C) package temperature ranges. Industrial versions are available in plastic DIP and PLCC; MIL versions are packaged in cerdip. Applications IF/RF signal processing Received Signal Strength Indicator (RSSI) High speed signal compression High speed spectrum analyzer ECM/radar
