Precision High Voltage Current Sense Amplifier is precision current sense amplifier that detect small differential voltages across a sense resistor in the presence of high input common mode voltages with a supply voltage Range from 2.7V to 12V. National Semiconductors India Designs Pvt Ltd is the manufacturer of Precision High Voltage Current Sense Amplifier. National Semiconductors India Designs Pvt Ltd, a wholly owned subsidiary of California-based National Semiconductor, manufactures and supplies innovative analog technology products that are energy-efficient and easy-to-use, with particular expertise in ultra low power designs.
The Precision High Voltage Current Sense Amplifier under series LMP8645 accepts input signals with common mode voltage Range from -2V to 42V, while the series LMP8645HV accepts input signal with common mode voltage Range from -2V to 76V. The LMP8645 and LMP8645HV have adjustable gain for applications where supply current and high common mode voltage are the determining factors. The gain is configured with a single resistor, providing a high level of flexibility, the accuracy could be as low as 2% [max] including the gain setting resistor. The output is buffered in order to provide low output impedance. This high side current sense amplifier is ideal for sensing and monitoring currents in DC or battery powered systems, excellent AC and DC specifications over temperature, and keeps errors in the current sense loop to a minimum. The LMP8645 is an ideal choice for industrial, automotive and consumer applications, and it is available in TSOT-6 package.
Application areas of Precision High Voltage Current Sense Amplifier are:
