Zero-Drift, Programmable Instrumentation Amplifier with Diagnostics, LMP8358, is a precision programmable-gain instrumentation amplifier. Its gain can be programmed to 10, 20, 50, 100, 200, 500, or 1000 through an SPI-compatible serial interface or through a parallel interface. Alternatively, its gain can be set to an arbitrary value using two external resistors. This instrumentation amplifier uses patented techniques to measure and continuously correct its input offset voltage, eliminating offset drift over time and temperature and the effect of 1/f noise. Zero-Drift, Programmable Instrumentation Amplifier with Diagnostics is manufactured by National Semiconductors India Designs Pvt Ltd.
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. Zero-Drift, Programmable Instrumentation Amplifier with Diagnostics has ground-sensing CMOS input that features a high CMRR and low input bias currents. It is capable of sensing differential input voltages in a common-mode range that extends from 100mV below the negative supply to 1.4V below the positive supply, making it an ideal solution for interfacing with ground-referenced sensors, supply-referenced sensor bridges, and any other application requiring precision and long-term stability. Additionally, the LMP8358 includes fault detection circuitry to detect open and shorted inputs and deteriorating connections to the signal source. Other features that make the LMP8358 a versatile solution for many applications are its rail-to-rail output, low input voltage noise and high gain-bandwidth product.
