PRODUCT DESCRIPTION
The AD626 is a low cost, true single-supply differential amplier
designed for amplifying and low-pass ltering small differential
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 amplier is equal to 6 (+VS – 1 V) which provides a
+24 V CMR while operating from a +5 V supply. Furthermore,
the AD626 features a CMR of 90 dB typ.
The amplier’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 supply. The
amplier provides a preset gain of 10, but gains between 10 and
100 can be easily congured with an external resistor. Further-
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 capacitor between the lter pin and analog ground.
The AD626A and AD626B operate over the industrial temperature
range of –40°C to +85°C.The AD626 is available in two 8-lead
packages: a plastic mini-DIP and SOIC.
