These circuits consist of four independent, high TSSOP14 (Thin Shrink Small Outline e Package) gain, intemally frequency compensated operation al amplifiers. They operate from a single power supply over a wide range of voltages. Operation

General Description de range of applica is local on card bypassing is needed only if the regulator is located far from 9 gulation, eliminating the distribution problems associated the filter capacitor of the power supply

一、如何知道机器行走的距离?

TWO-Terminal Ic DEVICES Temperature Transducer AD590 FEATURES PIN DESIGNATIONS Linear Current Output: 1 HA/K Wide Range:-55C to+150C Probe Compatible Ceramic Sensor Package

General Description hese devices need only one external com ation capacitor at the output. Tthe LM? aged in the to-220 power package and is capable applications requiring other voltages, see LM137 data 4 supplying 1.5A of output current These regulators employ internal current limiting safe area Features a Thermal, short circuit and sa tually all overload conditions
