有的电子芯片的后缀都不一样,虽然是同一种芯片,比如AD844AN AD844AQ的后缀AN和AQ都是什么意思,有哪些不同的地方.
A -> -40到1
A B J S 是耐温不同（工作环境）
N Q R 对应不同封装形式（外观不同）
The AD844 is available in four performance grades and three
package options.In the 16-pin SOIC (R) package,the AD844J
is specified for the commercial temperature range of 0°C to
+70°C.The AD844A and AD844B are specified for the industrial
temperature range of –40°C to +85°C and are available in
the cerdip (Q) package.The AD844A is also available in an 8-pin
plastic mini-DIP (N).The AD844S is specified over the military
temperature range of –55°C to +125°C.It is available in the
8-pin cerdip (Q) package.“A” and “S” grade chips and devices
processed to MIL-STD-883B,REV.C are also available.
