quick question regarding uc3846

guitar_joe · 13th September 2008, 02:17 PM

what's the difference between uc3846, uc2846 and uc1846..?
is there any difference?

From the datasheet, the UC1846 has a temperature range of -55 - 125°C, UC2846 -40 - 85°C and the UC3846 0 - 70°C.

The UC1846 and UC2846 have Identical characteristics other wise, and the UC3846 has some "relaxed" values. (basically the UC3846 is cheaper and made for consumer market.)

Joe,

Expanding on Fry's comments:

1846 = Military-Grade IC - REAL Expensive. Undergoes exhaustive testing each unit.
2846 = Industrial-Grade IC - Moderately expensive. Extensive testing, though not as strict as MIL-spec.
3846 = Consumer-Grade IC - cheap. See Fry's comments.
