AD620ARZ

The AD620ARZ is designed as one kind of low cost, high accuracy instrumentation amplifier that requires only one external resistor to set gains of 1 to 10,000.With its high accuracy of 40 ppm maximum nonlinearity, low offset voltage of 50 V max, and offset drift of 0.6 V/°C max, the AD620ARZ is ideal for use in precision data acquisition systems, such as weigh scales and transducer interfaces.

Features of the AD620ARZ are:(1)gain set with one external resistor;(2)wide power supply range (±2.3 V to ±18 V);(3)higher performance than 3 op amp IA designs;(4)available in 8-lead DIP and SOIC packaging;(5)low power, 1.3 mA max supply current;(6)50 V max, input offset voltage;(7)100 dB min common-mode rejection ratio (G=10);(8)1.0 nA max, input bias current;(9)15 s settling time to 0.01%.And it can be used in weigh scales, ECG and medical instru-mentation, transducer interface, data acquisition systems, industrial process controls and battery-powered and portable equipment.

The absolute maximum ratings of the AD620ARZ can be summarized as:(1)supply voltage:±18 V;(2)internal power dissipation:650 mW;(3)input voltage (common-mode):±Vs;(4)differential input voltage:25 V;(5)output short-circuit duration:indefinite;(6)storage temperature range (N, R):-65°C to +125°C;(7)operating temperature range:-40°C to +85°C;(8)lead temperature range (soldering 10 seconds):300°C.If you want to know more information such as the electrical characteristics about the AD620ARZ,please download the datasheet in www.seekic.com or www.chinaicmart.com .
