FEATURES

DESCRIPTION

The LMP8602 and LMP8603 are fixed gain precision

amplifiers. The parts 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 a 3.3V supply, the input common

mode voltage range is from –4V to +27V. The

LMP8602 and LMP8603 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

parts that are shown in the tables are 100% tested

and all bold values are also 100% tested over

temperature.

The parts have a precise gain of 50x for the

LMP8602 and 100x for the LMP8603, which are

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 5x for the LMP8602 and 10x for the LMP8603. 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.
