(no external capacitance is required.) with an offset voltage of only 5v and drift less than 0.03v/c, the AD8551 is perfectly suited for applications where error sources cannot be tolerated. position and pressure sensors, medical equipment, and strain gage amplifiers benefit greatly from nearly zero drift over their operating temperature range. many more systems require the rail-to-rail input and output swings provided by the ad855x family. the AD8551 / 52/54 family is specified for the extended industrial ( -40 to +125c) temperature range. the AD8551 single and ad8552 dual amplifiers are available in 8- p in plastic dip and so surface mount packages . the ad8554 quad is available in the 14-pin dip, and narrow 14-pin packages. o u t a - i n a + i n a v - v + o u t b - i n b + i n b 1 2 3 4 5 6 7 1 4 1 3 1 2 1 1 1 0 9 8 - + - + - + - + a d 8 5 5 4 - + - + 1 2 3 4 8 7 6 5 v + o u t b - i n b + i n b o u t a - i n a + i n a v - o u t a - i n a + i n a v + v - o u t d - i n d + i n d o u t c + i n c - i n c + i n b - i n b o u t b 8 - l e a d e p o x y d i p ( n s u f f i x ) 1 4 - l e a d n a r r o w - b o d y s o ( n s u f f i x ) 1 4 - l e a d e p o x y d i p ( n s u f f i x ) 8 - l e a d s o ( r s u f f i x ) a d 8 5 5 2 a d 8 5 5 4 a d 8 5 5 2 n o t e : p i n o r i e n t a t i o n i s e q u i v a l e n t f o r e a c h p a c k a g e v a r i a t i o n n u l l - i n a + i n a v - n c v + o u t a n u l l a d 8 5 5 1 8 - l e a d s o ( r s u f f i x ) a d 8 5 5 1 1 2 3 4 8 7 6 5 8 - l e a d e p o x y d i p ( n s u f f i x ) n c v + o u t a n u l l n u l l - i n a + i n a v -
