LM158-LM258-LM358 LM158A-LM258A-LM358A Low Power Dual Operational Amplifiers ■ Internally frequency compensated ■ Large DC voltage gain: 100dB ■ Wide bandwidth (unity gain): 1.1mHz (temperature compensated) ■ Very low supply current/op (500µA) essentially independent of supply voltage ■ Low input bias current: 20nA (temperature compensated) ■ Low input offset voltage: 2mV ■ Low input offset current: 2nA ■ Input common-mode voltage range includes ground ■ Differential input voltage range equal to the power supply voltage ■ Large output voltage swing 0V to (Vcc - 1.5V) Description These circuits consist of two independent, high- gain, internally frequency-compensated which were designed specifically to operate from a single power supply over a wide range of voltages. The low power supply drain is independent of the magnitude of the power supply voltage. Application areas include transducer amplifiers, DC gain blocks and all the conventional op-amp circuits which now can be more easily implemented in single power supply systems. For example, these circuits can be directly supplied with the standard +5V which is used in logic systems and will easily provide the required interface electronics without requiring any additional power supply. In the linear mode the input common-mode voltage range includes ground and the output voltage can also swing to ground, even though operated from only a single power supply voltage.

Power dissipation must be considered to ensure maximum junction temperature (Tj) is not exceeded. 2. Short-circuits from the output to VCC can cause excessive heating if VCC > 15V. The maximum output current is approximately 40mA independent of the magnitude of VCC. Destructive dissipation can result from simultaneous short-circuit on all amplifiers. 3. This input current only exists when the voltage at any of the input leads is driven negative. It is due to the collector-base junction of the input PNP transistor becoming forward biased and thereby acting as input diodes clamps. In addition to this diode action, there is also NPN parasitic action on the IC chip. this transistor action can cause the output voltages of the Op-amps to go to the VCC voltage level (or to ground for a large overdrive) for the time duration than an input is driven negative. This is not destructive and normal output will set up again for input voltage higher than -0.3V. 4. Short-circuits can cause excessive heating. Destructive dissipation can result from simultaneous short-circuit on all amplifiers 5. Human body model, 100pF discharged through a 1.5kΩ resistor into pin of device. 6. Machine model ESD, a 200pF cap is charged to the specified voltage, then discharged directly into the IC with no external series resistor (internal resistor < 5Ω), into pin to pin of device. 3/16 Typical Application Schematic LM158-LM258-LM358-LM158A-LM258A-LM358A 2 Typical Application Schematic Figure 1.

LM3S8962评估板原理图分析(连载中。。。)
最近有一个板子刚好要用到群星系列的MCU,看到坛子有这个活动,就认领了分析原理图的任务,和大伙一起讨论。 初步想法:把原理图分成几个模块,一步一步分析,先最小系统,再其他单元,最后单板接口。 我是ARM-Cortex-M3初学者,手上也没有这块板的实物,分析难免有一些错误,请大家多多指教!   附LM3S8962评估板实物图(从
