General Description
The LMP8601 and LMP8601Q are fixed 20x gain precision amplifiers. The part will amplify and filter small differential signals
in the presence of high common mode voltages. The input common mode voltage range is –22V to +60V when operating from a single
5V supply. With 3.3V supply, the input common mode voltage range is from –4V to +27V. The LMP8601 and LMP8601Q are members
of the Linear Monolitic Precision (LMP
®) family and are ideal parts for unidirectional and bidirectional current sensing applications. All parameter values of the
part that are shown in the tables are 100% tested and all bold values are also 100% tested over temperature.
The part has a precise gain of 20x which is adequate in most targeted applications to drive an ADC to its 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. The connection between the two stages of the signal path is brought out on two pins to enable the possibility
to create an additional filter network around the output buffer amplifier. These pins can also be used for alternative configurations
with different gain as described in the applications section .
The mid-rail offset adjustment pin enables the user to use these devices for bidirectional single supply voltage current sensing.
The output signal is bidirectional and mid-rail referenced when this pin is connected to the positive supply rail. With the
offset pin connected to ground, the output signal is unidirectional and ground-referenced .
The LMP8601Q incorporates enhanced manufacturing and support processes for the automotive market, including defect detection
methodologies. Reliability qualification is compliant with the requirements and temperature grades defined in the AEC Q100
standard.
