PROD UCT DE SCRIP TION

The AD626 is a low cost, true sin gle-sup ply dif fer en tial am pli ﬁ er

de signed for am pli fy ing and low-pass ﬁ 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 ampliﬁ er is equal to 6 (+V

+24 V CMR while operating from a +5 V sup ply. Fur ther more,

the AD626 features a CMR of 90 dB typ.

The ampliﬁ er’s inputs are protected against continuous overload of

up to 50 V, and RFI ﬁ 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

ampliﬁ er provides a preset gain of 10, but gains be tween 10 and

100 can be easily con ﬁ 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 ﬁ lter capability by

connecting a ca pac i tor between the ﬁ 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 AD626 is available in two 8-lead

packages: a plastic mini-DIP and SOIC.
