LMP8358 is a high-precision programmable gain meter amplifier of the LMP high-precision amplifier series in one country. Its gain can be programmed to 10, 20, 50, 100, 200, 500 or 1000 via an SPI-compatible serial interface or via a parallel interface. In addition, its gain can be set to any value, using two external resistors. LMP8358 measures with patented technology and continuously corrects its input offset voltage, eliminating the effects of offset drift, over time and temperature and 1/f noise. Its ground remote sensing CMOS input features high CMRR and low input bias current. Its ability to sense a common mode range extension of 1.4V differential input voltage below the positive supply voltage of 100mV below the negative supply voltage makes it an ideal solution with a ground reference sensor, a bridge interface to the reference sensor, any other application, requiring accuracy and long-term stability. In addition, LMP8358 includes fault detection circuitry to detect inputs for open and short circuits and deteriorating connected sources. Other features that make LMP8358 a versatile solution for many applications are its rail-to-rail output, low input voltage noise, and high gain bandwidth product.
