AD8310ARMZ

The AD8310ARMZ is designed as a complete, dc-440 MHz demodulating logarithmic amplifier (log amp) with a very fast voltage mode output, capable of driving up to 25 mA into a grounded load in under 15 ns. It uses the progressive compression (successive detection) technique to provide a dynamic range of up to 95 dB to ±3 dB law conformance or 90 dB to a ±1 dB error bound up to 100 MHz. Application is conversion of signal level to decibel form, transmitter antenna power measurement, receiver signal strength indication (RSSI), low cost radar and sonar signal processing, network and spectrum analyzers, signal-level determination down to 20Hz and true-decibel ac mode for multimeters.

It has ten features. (1) Multistage demodulating logarithmic amplifier. (2) Voltage output, rise time <15ns. (3) High current capacity: 25mA into grounded RL. (4) 95dB dynamic range: -91dBV to +4dBV. (5) Single supply of 2.7V min at 8mA typ. (6) DC440 MHz operation, ±0.4dB linearity. (7) Slope of +24mV/dB, intercept of -108dBV. (8) Highly stable scaling over temperature. (9) Fully differential dc-coupled signal path. (10) 100ns power-up time, 1mA sleep current. That are all the main features.

Some absolute maximum ratings have been concluded into several points as follow. (1) Its supply voltage would be 7.5V. (2) Its input power single-ended (re: 50) would be 18dBm. (3) Its differential drive would be 22dBm. (4) Its internal power dissipation would be 200mW. (5) Its JA would be 200°C/W. (6) Its maximum junction temperature would be 125°C. (7) Its operating temperature range would be from -40°C to +85°C. (8) Its storage temperature range would be from -65°C to +150°C. (9) Its lead temperature (soldering 60 sec) would be 300°C. It should be noted that stresses above those listed under absolute maximum ratings may cause permanent damage to the device. And so on.
