The ADA4661-2-KGD performance is guaranteed at 3.0 V, 10 V, and 18 V power supply voltages. It uses the Analog Devices, Inc., patented Digi Trim® trimming technique, which achieves low offset voltage. Additionally, the unique design architecture of the ADA4661-2-KGD allows it to have excellent power supply rejection, mon-mode rejection, and offset voltage when operating in the mon-mode voltage range of - VSY + 1.5 V to +VSY - 1.5 V. The ADA4661-2-KGD is specified over the extended industrial temperature range (- 40°C to +125°C). Additional application and technical information can be found in the ADA4661-2 data sheet. Known Good Die (KGD): these die are guaranteed to data sheet specifications. Figure 1.
