The LM139 series consists of four independent precision voltage comparators with an offset voltage specification as low as 2 mV max for all four comparators. These were designed specifically to the operation from a single power supply over a wide range of voltages. 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. These comparators also have a unique characteristic in that the input common-mode voltage range includes ground, even though operated from a single power supply voltage. The LM139 series was designed to directly interface with TTL and CMOS. When operated from both plus and minus power supplies, they will directly interface with MOS logic— where the low power drain of the LM339 is a distinct advantage over standard comparators. These devices consist of four independent voltage comparators that are designed to operate from a single power supply over a wide range of voltages. Operation from dual supplies also is possible, as long as the difference between the two supplies is 2 V to 36 V, and VCC is at least 1.5 V more positive than the input common-mode voltage. Current drain is independent of the supply voltage. The outputs can be connected to other open-collector outputs to achieve wired-AND relationships. The LM139 and LM139A are characterized for operation over the full military temperature range of –55°C to 125°C. The LM239 and LM239A are characterized for operation from –25°C to 125°C. The LM339 and LM339A are characterized for operation from 0°C to 70°C. The LM2901, LM2901AV, and LM2901V are characterized for operation from –40°C to 125°C.

LM358 LM358 IC is a low-power dual-operational amplifier integrated circuit . It can support an operating voltage of +3 to +32 volts or ±1.5 to ±16 volts and input voltage can range from ?0.3 to +32 volts with a single power supply. LM 358B and LM2904B devices are the next-generation versions of LM 358 and LM2904 operational amplifiers which include two high-voltage (36 V) op-amps. The LM 358 and LM2904 are available in a chip-sized package (8-bump DSBGA) using TI's DSBGA package technology. Utilizing the circuit designs perfected for Quad Operational Amplifiers, these dual operational amplifiers feature low power drain, a common mode input voltage range extending to ground/VEE, and single supply or split supply operation. The LM358 IC series is compatible with industry-standard operational amplifiers, making it a popular choice in cost-sensitive applications. It 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. LM 358 IC can also be used for testing an LDR, a phototransistor, and a photodiode. When it comes to the LM 358 IC, we prioritize quality and affordability above all else. That's why we're excited to offer you not only the IC but also the best LM358 price available anywhere online!

3Kg Load Cell The electrical signal output is typically in the order of a few millivolts and requires amplification by an instrumentation amplifier before it can be used. The output of the transducer is plugged into an algorithm to calculate the force applied to the transducer. A load cell is a transducer that is used to create an electrical signal whose magnitude is directly proportional to the force being measured.
