... The laser trimming process which provides the excellent linear- ity is also used to trim both the absolute value and the tempera- ture coefficient of the reference of the AD565A resulting in a typical full-scale gain ppm/°C. When tighter TC per- formance is required or when a system reference is available, the AD566A may be used with an external reference. *Covered by Patent Nos.: 3,803,590 ...
