illustrate

The LMP8601 and LMP8601Q are fixed 20x gain precision amplifiers. Some 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. 3.3 V supply with input common-mode voltage range from -4V to 27 V. LMP8601 and LMP8601Q members' linear single-chip high precision (LMP ® Ideal place for homes and unidirectional and bidirectional current sensing applications. All the parameter values shown in the table are 100% tested and all bold values are also over 100% temperature test.

The device has an accurate gain that is 20 times the full-scale value of the ADC that is sufficient to drive the ADC for the most targeted applications. Fixed gain is achieved in two different stages, the preamplifier, a gain of 10x and an output stage buffer amplifier with a gain of 2x. 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 LMP8601Q greatly enhances the production automotive market and support processes, including defect detection methods. Reliability qualification meets the requirements and temperature grades defined in the AEC Q100 standard.
