简  介:a FEATURES EASY TO USE Pin-Strappable Gains of 10 and 100 All Errors Specified for Total System Performance Higher Performance than Discrete In Amp Designs Available in 8-Lead DIP and SOIC Low Power, 1.3 mA Max Supply Current Wide Power Supply Range ( 2.3 V to 18 V) EXCELLENT DC PERFORMANCE 0.15% Max, Total Gain Error 5 ppm/ C, Total Gain Drift 125 V Max, Total Offset Voltage 1.0 V/C Max, Offset Voltage Drift LOW NOISE 9 nV/√ Hz, @ 1 kHz, Input Voltage Noise 0.28 V p-p Noise (0.1 Hz to 10 Hz) EXCELLENT AC SPECIFICATIONS 800 kHz Bandwidth (G = 10), 200 kHz (G = 100) 12 s Settling Time to 0.01% APPLICATIONS Weigh Scales Transducer Interface and Data Acquisition Systems Industrial Process Controls Battery-Powered and Portable Equipment PRODUCT DESCRIPTION Low Drift, Low Power Instrumentation Amplifier AD621 CONNECTION DIAGRAM 8-Lead Plastic Mini-DIP (N), Cerdip (Q) and SOIC (R) Packages G = 10/100 1 –IN 2 +IN 3 8 G = 10/100 +VS AD621 7 TOP VIEW 6 OUTPUT (Not to Scale) 5 REF –VS 4 gain drift errors are achieved by the use of internal gain setting resistors. Fixed gains of 10 and 100 can easily be set via external pin strapping. The AD621 is fully specified as a total system, therefore, simplifying the design process. For portable or remote applications, where power dissipation, size, and weight are critical, the AD621 features a very low supply current of 1.3 mA max and is packaged in a compact 8-lead SOIC, 8-lead plastic DIP or 8-lead cerdip. The AD621 also excels in a……
