Texas Instruments LMP8602 / LMP8603 60V Fixed Gain Current Sensing Amplifiers

Texas Instruments LMP8602 and LMP8603 60V fixed gain current sensing precision amplifiers amplify and filter small differential signals in the presence of high common mode voltages. The input common mode voltage range of these TI devices is -22V to +60V when operating from a single 5V supply. With a 3.3V supply, the input common mode voltage range is from -4V to +27V. TI LMP8602 and LMP8603 fixed gain current sensing precision amplifiers are members of LMP® family and are ideal for use in unidirectional and bidirectional current sensing applications. The LMP8602 has a precise gain of 50x while the LMP8603 has a precise gain of 100x. These precise gain figures can drive an ADC to its full scale value in most targeted applications. The LMP8602Q and LMP8603Q incorporate enhanced manufacturing and support processes for the automotive market, including defect detection methodologies.
