AD626A Low Cost, Single Supply Differential Amplifier
Brand: Analog Devices · SKU: AD626A · MPN: AD626A · Category: Components
The AD626A is a low cost, true single-supply differential amplifier designed for amplifying and low-pass filtering small differential voltages from sources having a large common-mode voltage. It 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 is equal to 6 (+VS – 1 V), providing a +24 V CMR while operating from a +5 V supply. The AD626 features a CMR of 90 dB typ. Its inputs are protected against continuous overload of up to 50 V, and RFI filters are included in the attenuator network. The output range is +0.03 V to +4.9 V using a +5 V supply. It provides a preset gain of 10, but gains between 10 to 100 can be easily configured with an external resistor. A gain of 100 is available by connecting the G = 100 pin to analog ground. The AD626 also offers low-pass filter capability by connecting a capacitor between the filter pin and analog ground. The AD626A and AD626B operate over the industrial temperature range t
