Analog Devices has developed a novel, patented trimming process that delivers the required accuracy and performance at a very low cost. The DigiTrim™ technique allows production of precision CMOS amplifiers at costs up to 30% lower than competing solutions and with higher accuracy. This technique also allows digital control of resistor values for current matching which can bring offset voltage values under 500μV over the full common mode input voltage range (AD8602 specifically).
