Question
I have one AD652JP(20 pin, PLCC package) on hand, and when I measured the input resistors, the result was same as datasheet.But I am not sure whether the military version AD652SE/883B(20 pin, LCC package) has the same specifications and functions, for example pinconfigurations and input resistor, etc. It is not said clearly in datasheet. Could you please help confirm it.
Answer
I have checked the pinout of the 20-lead LCC package and it is different to the 20-lead PLCC package. The pinout for the LCC package isPIN NO. FUNCTION1 NC2 +Vs3 TRIM4 TRIM5 OP-AMP OUT6 NC7 OP-AMP-8 OP-AMP+9 10V INPUT10 -Vs11 NC12 Cos13 CLOCK INPUT14 FREQ OUT15 DIGITAL GROUND16 NC17 ANALOG GROUND18 COMP'-'19 COMP'+'20 COMP REFNC = No Connect.The LCC option does not have the 8V, 5V options that the PLCC part has so, all the resistance options listed are not valid. The 10V option will havethe same resistance as the PLCC part.
