The  AD626ARZ-REEL  is a low cost, true sin gle-sup ply dif fer en tial am pli ?  er de signed for am pli fy ing and low-pass ?ltering small dif fer en tial voltages from sources having a large common-mode voltage.The AD626 can operate from either a single supply of +2.4 V to +10 V, or dual supplies of ±1.2 V to ±6 V. The input common-mode range of this ampli?er is equal to 6 (+VS – 1 V) which pro vides a +24 V CMR while operating from a +5 V sup ply. Fur ther more, the AD626 features a CMR of 90 dB typ.The ampli?er’s inputs are protected against continuous overload of up to 50 V, and RFI ?lters are included in the attenuator network. The output range is +0.03 V to +4.9 V using a +5 V sup ply. The ampli?er provides a preset gain of 10, but gains be tween 10 and 100 can be easily con ?g ured with an external re sis tor. Fur ther -more, a gain of 100 is available by connecting the G = 100 pin to analog ground. The AD626 also offers low-pass ?lter capability by connecting a ca pac i tor between the ?lter pin and analog ground.The AD626A and AD626B operate over the industrial tem per a ture range of –40°C to +85°C. The AD626ARZ-REEL  is available in two 8-lead packages: a plastic mini-DIP and SOIC.
