Part#: LMP8601MA
Manufacturer: Texas Instruments High-Performance Analog

Description: Operational Amplifier, 1 Func, 1000uV …

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 Monolithic 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
