illustrate

The LMP8602 and LMP8603 are fixed-gain precision amplifiers. section will amplify and filter the presence of small differential signals at high common-mode voltages. The input common-mode voltage range is -22 V to +60 V from a single 5 V supply. It operates from a 3.3 V supply and has an input common-mode voltage range of -4 V to 27 V. The LMP8602 and LMP8603 are members of the linear single-chip high precision (LMP). ® Ideal place for homes and unidirectional and bidirectional current sensing applications. In the section shown in the table, all parameter values are 100% tested and all bold values are also over 100% temperature test.

The device has an accurate gain of 50X for the LMP8602 and 100x for the LMP8603, which is the most targeted application to provide enough to drive the full scale value of the ADC. Implement two different stages, with a gain of 10x and an output stage of 5x the LMP8602 and a gain of 10X of the LMP8603 to buffer the amplifier's fixed gain of the preamplifier. The connection of the signal path between the two stages brings two pins that make it possible to cause additional output buffers around the filter network around the amplifier. These pins can also use different gains, as described in the alternative configurations described in the Applications section.

The mid-rail offset adjustment pin enables the user to use these devices to sense bidirectional single-supply voltage and current. The output signal is bidirectional, and this pin is referenced when connected to the positive rail when the middle rail is referenced. With the bias pin connected to ground, the output signal is unidirectional and referenced to ground.

The LMP8602 and LMP8603 are available in an 8-pin SOIC package and an 8-pin MSOP package.

The LMP8602Q and LMP8603Q are incorporated into the automotive market and support processes to enhance production, including defect detection methods. Reliability qualification meets the requirements and temperature grades defined in the AEC Q100 standard.
