Voltage and current sensing in HEV/EV applications Low-side current sensing for high-performance cost-sensitive applications How to lay out a PCB for high-performance, low-side current-sensing designs J)ĭesign Guidelines for Devices with LM324/LM358 Cores (Rev. LMx58-N Low-Power, Dual-Operational Amplifiers datasheet (Rev. The LM358 and LM2904 are available in a chip-sized package (8-bump DSBGA) using TIs DSBGA package technology. For example, the LM158 series can be directly operated off of the standard 3.3-V power supply voltage which is used in digital systems and will easily provide the required interface electronics without requiring the additional ☑5-V power supplies. 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.Īpplication 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. The LM158 series consists of two independent, high gain, internally frequency compensated operational amplifiers which were designed specifically to operate from a single power supply over a wide range of voltages. Power drain suitable for battery operation.Allows direct sensing near GND and V OUT also goes to GND.The input bias current is also temperature compensated.The unity gain cross frequency is temperature compensated.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.Differential input voltage range equal to the power supply voltage.Input common-mode voltage range includes ground.Very low supply current drain (500 ♚) essentially independent of supply voltage.
