SL531AC

The SL531AC is designed as one kind of a wide band amplifiers for use in logarithmic IC amplifiers of the long type. The input and log output of a true log amplifier are at the same frequency i.e. detection does not occur. The small signal is 10dB and bandwidth is over 500MHz. At high signal levels the gain of a single stage drops to unity. Acaacade of such stages give a close approximation to a log characteristic at centre frequencies between 10 and 200MHz.

SL531AC has five features. (1)Low phase shift vs amplitude. (2)On-chip supply decoupling. (3)Low external components count. (4)MIL-M-38510 change notification observed. (5)Full quality conformance inspection. Those are all the main features.

Some SL531AC absolute maximum ratings have been concluded into several points as follow. (1)Its supply voltage would be 15V. (2)Its storage temperature range would be from -55°C to 150°C. (3)Its operating temperature range would be from -55°C to 125°C. (4)Its max junction temperature would be 175°C. (5)Its junction to ambient thermal resistance would be 210°C/W. (5)Its junction to case thermal resistance would be 60°C/W. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some SL531AC electrical characteristics are concluded as follow. (1)Its small signal voltage gain would be min 7.5dB and max 12.5dB. (2)Its high level slope gain would be min -1.2dB and typ 0dB and max +1.2dB. (3)Its upper cut off frequency would be min 250MHz. (4)Its lower cut off frequency would be max 10MHz. (5)Its supply current would be max 25mA. (6)Its phase change with input amplitude would be min -2° and max +2° for sub group 4 and would be min -4° and max +4° for sub group 5,6. And so on.
