Note 1: For high temperature at high temperature In the next operation, LM358/LM358A, LM2904 must be based on A+125 ; C's maximum mDIP resistor is 120 ; C/W, and metal cans are 182 ; C/C/W, the small shape is encapsulated to 189 ; C/W, and the miniature SMD is 230 ; C/W. It is suitable for welding equipment to work in a printed circuit board and work in a static air environment. LM258/LM258A and LM158/LM158A can be reduced according to the highest junction temperature A+150 ; C. The dissipation is the sum of the two amplifiers-as much as possible to use the external resistor as much as possible so that the amplifier is saturated or reduced in the integrated circuit.
Note 2: The short circuit from output to V+may cause overheating and eventually cause damage. When considering the short circuit of the ground, the maximum output current is about 40 mA, which has nothing to do with the size of V+. When the voltage value of the power supply exceeds+15V, the continuous short circuit may exceed the rated value of the power loss and cause the final damage. Destructive dissipation can be caused by short circuits at the same time.
Note 3: Only when the voltage on the lead is negatively drives, the input current exists. This is because the transistor caused by the input PNP's collector base pole becomes a positive bias, which plays the role of input diode clamping. In addition to the role of this diode, the role of horizontal NPN parasitic transistors is on the IC chip. This action of the transistor will cause the output voltage of the operation amplifier to reach the V+voltage level (or the large -drived ground ground) input for a period of time. This is not destructive. When the input voltage is negative, the normal output state will be re -established than the 0.3V (when 25 ; C).Note 4: For LM158/LM158A, these specifications are limited to 55 ; c≤ta ≤+125 ; c.

Note 6: Due to the PNP input level, the direction of the input current exceeds IC. This current is basically constant, and there is no loading change on the input bank of the output states.
Note 7: The negative value of the input co -mode voltage of any input signal voltage shall not exceed 0.3V (at 25 ; C). The upper -end co -mode voltage range is V+ 1.5V (at 25 ; C), but any input or two inputs can reach+32V without damage (+26VFor LM2904), and V+.
Note 8: Since the external component is close, it is necessary to ensure that the coupling is not generated by the strange capacitors between these external components. This can usually be detected when this type of capacitor is increased at a higher frequency.

Typical performance features
Program prompt
The LM158 series is an operational amplifier. It only uses a single power supply voltage, has real differential input, and uses the input co -mode to maintain a linear mode 0 VDC voltage. The operating range of these amplifiers is very small. At 25 ; C, the amplifier may stop working at 2.3 VDC. Preventive measures should be taken to ensure that the power supply will never upside down because of the polarity of the integrated circuit or the device is not inadvertently installed backwards in the test socket as an infinite current surging through the IC as an unlimited rodent. The large differential input voltage can be easily adapted and the diode that protects the diode as the input differential voltage is that there is no large input current from the large difference input voltage. Differential input voltage may be greater in the absence of damaged equipment. Protection should be used to prevent the input voltage from becoming more than 0.3 VDC (when 25 ; C). Enter a clamping diode to use the resistor at the IC input terminal. In order to reduce the power consumption of the power supply, the amplifier provides a small signal level to provide A -level output levels to convert the A mode into a class B signal. This makes the output current of the amplifier source and Huida. Therefore, both NPN and PNP external current boost transistors can be used to expand the power capacity amplifier of BASIC. The output voltage needs to be increased by about one diode to above the ground. The vertical PNP output current on the bias chip decreases the transistor. For AC applications, the load capacitance couples to the output of the amplifier, and a resistor should be used to increase the output of the ground to the ground to increase the A -class bias current and prevent cross distortion.
Where is the load directly coupling, in DC applications, there is no cross distortion. Directly applied to the amplifier to reduce the stability of the loop. The value of 50pf can be connected with non -reversal in the worst case. If a large closed -loop gain or resistance must be used by a large load capacitor, it should be driven by the amplifier. The bias network of LM158 establishes the size of the drain current and the power supply. The voltage is not more than 3 VDC to 30 VDC. The short -circuit of the output or the short -circuit supply time of the positive power supply should be short. The device can be power off, not due to short -circuit currentThe melting of the metal is due to the large increase in the IC chip due to the high functional temperature and the final failure. When connecting to a direct short -circuit, multiple amplifiers will increase the total integrated circuit. If it does not use a series of external dispersion restricted resistors for appropriate protection, the power loss reaches the output lead of the amplifier with a damage level. The output source current that can be used at a larger value of 25 ° C provides a larger output current capacity (see typical performance characteristics) at high temperature (see typical performance characteristics) than the standard integrated circuit operational amplifier. The circuit introduced in the typical application chapter emphasizes only under a single power supply voltage. If there is a supplementary power supply, all the standard operation can be used. Generally speaking, a pseudo -jacking (Vi's bias voltage benchmark+/2) is introduced to the operating supply system that is higher or lower than this value among the single power supply. Many application circuits use wide input co -mode voltage range including the ground. In most cases, the input bias does not require the range of the input voltage and can be easily adapted.
