LT1088

The LT1088 is a kind of thermally based RMS-DC converter building block. It converts the input waveform to heat. The typical applications include: (1)wideband RMS voltmeters; (2)RF leveling loops; (3)wideband AGC; (4)high crest factor measurements; (5)SCR power monitoring.

There are some features of LT1088as follows: (1)300 MHz 3 dB bandwidth; (2)1% accuracy DC-50 MHz; (3)2% to 100 MHz; (4)bandwidth flat over input voltage range; (5)50:1 crest factor; (6)20:1 dynamic range; (7)35 V peak input; (8)thermally based operation; (9)fully speciified thermal and electrical parameters; (10)standard IC packages; (11)resistive inputs.

The last one is the maximum ratings of LT1088: (1)voltage on any pin: V- + 40 V to V-; (2)voltage from channel A to channel B: 100 V; (3)reverse diode voltage: 3.5 V; (4)forward diode current: 15 mA; (5)input power (25): 0.375 W; (6)peak input power (30 sec): 0.435 W; (7)maximum die temperature: 150; (8)peak die temperature (30 sec): 175; (9)functional temperature range: -55 to 125; (10)operating temperature range: -40 to 85; (11)lead temperature (soldering, 10 sec): 300.
