Description

The SV8541A/SV8542A/SV8544A consist of 1/2/4 independent, high gain, internally frequency- compensated operational amplifiers. They operate from a single power supply ranging from +1.8V to +5.5V and consume very low current that make them idea for two to four battery powered applications. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage. The family also features low noise, low output offset voltage, low input offset current and low input bias current that make the family idea for sensor application within noisy environment Order codes Part number Operation range Package Packing SV8541A-05SC-TR3 -40°C, +85°C SC70-5 Tape & reel, 3000pcs SV8541A-05OT-TR3 SOT23-5 Tape & reel, 3000pcs SV8542A-08SP-TR2 SOP-8 Tape & reel, 2500pcs SV8542A-08MP-TR2 MSOP-8 Tape & reel, 2500pcs SV8544A-14TP-TR2 TSSOP-14 Tube, 56ea / tube, 6720ea / carton SV8544A14SP-TR2 SOP-14 Tube, 56ea / tube, 6720ea / carton

This is a stress rating only; functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. CAUTION This integrated circuit can be damaged by ESD if you don’t pay attention to ESD protection. SAVITECH recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
