LMP8603MME/NOPB

具有直列式滤波器功能的 -22V 至 60V、双向电流感应放大器 8-VSSOP -40 to 125

The LMP8601, LMP8602, LMP8603 LMP860x and LMP8601-Q1, LMP8602-Q1, LMP8603-Q1 LMP860x-Q1 devices are fixed-gain, precision current-sense amplifiers also referred to as current-shunt monitors. The input common-mode voltage range is –22 V to +60 V when operating from a single 5-V supply, or –4 V to +27 V with a 3.3-V supply. The LMP860x and LMP860x-Q1 are ideal parts for unidirectional and bidirectional current sensing applications.

These devices have a precise gain of 20x LPM8601, LPM8601-Q1, 50x LPM8602, LPM8602-Q1, and 100x LPM8603, LPM8603-Q1, and are adequate in most targeted applications to drive an ADC to full-scale value. The fixed gain is achieved in two separate stages: a preamplifier with a gain of 10x and an output stage buffer amplifier with a gain of 2x LMP8601, LMP8601-Q1, 5x LMP8602, LMP8602-Q1, or 10x LMP8603, LMP8603-Q1. The path between the two stages is brought out on two pins to enable the option of an additional filter network or modifying the gain.

The offset input pin enables these devices for unidirectional or bidirectional single supply voltage current sensing.

The LMP860x-Q1 devices incorporate enhanced manufacturing and support processes for the automotive market and are compliant with the AEC-Q100 standard.
