(2) recommended operating conditions these conditions represent a range within which the expected characteristics of the ic can be approximately obtained. the electrical characteristics are guaranteed under the conditions of each parameter. (3) reverse connection of power supply connecting the power supply in reverse polarity can damage the ic. take precautions against reverse polarity when connecting the power supply, such as mounting an external diode between the power supply and the ic?s power supply terminals. (4) power supply lines design the pcb layout pattern to provide low impedance ground and supply lines. separate the ground and supply lines of the digital and analog blocks to prevent noise in the ground and supply lines of the digital block from affecting the analog block. furthermore, connect a capacitor to ground at all power supply pins. consider the effect of temperature and aging on the capacitance value when using electrolytic capacitors. (5) ground voltage the voltage of the ground pin must be the lowest voltage of all pins of the ic at all operating conditions. ensure that no pins are at a voltage below the ground pin at any time, even during transient condition. (6) short between pins and mounting errors be careful when mounting the ic on printed circuit boards. the ic may be damaged if it is mounted in a wrong orientation or if pins are shorted together. short circuit may be caused by conductive particles caught between the pins. (7) operation under strong electromagnetic field operating the ic in the presence of a strong electromagnetic field may cause the ic to malfunction. (8) testing on application boards when testing the ic on an application board, connecting a capacitor directly to a low-impedance output pin may subject the ic to stress. always dischar ge capacitors completely after each pr ocess or step. the ic?s power supply should always be turned off completely before connecting or removing it from the test setup during the inspection process. to prevent damage from static discharge, ground the ic during assembly and use similar precautions during transport and storage. (9) regarding input pins of the ic this monolithic ic contains p+ isolation and p substrat e layers between adjacent elements in order to keep them isolated. p-n junctions are formed at the intersection of th e p layers with the n layers of other elements, creating a parasitic diode or transistor. for example (refer to figure below): when gnd > pin a and gnd > pin b, the p-n junction operates as a parasitic diode. when gnd > pin b, the p-n junction operates as a parasitic transistor. parasitic diodes inevitably occur in the structure of the ic. the operation of parasitic diodes can result in mutual interference among circuits, operational faults, or physical damage. therefore, conditions that cause these diodes to operate, such as applying a voltage lower than the gnd voltage to an input pin (and thus to the p substrate) should be avoided. resistor transistor (npn) n n n p + p + p p substrate gnd parasitic element pin a n n p + p + p p substrate gnd parasitic element pin b c b e n gnd pin a pin b other adjacent elements e b c gnd parasitic element figure 41. example of monolithic ic structure

(11)external capacitor when using a ceramic capacitor, determine the dielectric constant considering the change of capacitance with temperature and the decrease in nominal capacitance due to dc bias and others. (12)thermal shutdown circuit (tsd) the ic incorporates a built-in thermal shutdown circuit, which is designed to turn off the ic when the internal temperature of the ic reaches a specified value. do not contin ue to operate the ic after this function is activated. do not use the ic in conditions where this function will always be activated. (13) thermal consideration use a thermal design that allows for a sufficient margin by taking into account the permissible power dissipation (pd) in actual operating conditions. consider pc that does not exceed pd in actual operating conditions (pc pd). package power dissipation : pd (w)=(tjmax ta ) / ja power dissipation : pc (w)=(vcc vo) io+vcc ib tjmax : maximum junction temperature=150 , ta : peripheral temperature[ ] , ja : thermal resistance of package-ambience[ /w], pd : package power dissipation [w], pc : power dissipation [w], vcc : input voltage, vo : output voltage, io : load, ib : bias current
