SNOSAR2E –SEPTEMBER 2008–REVISED MARCH 2013

60-V Common-Mode Bidirectional Precision Current Sensing Amplifier

Check for Samples: LMP8601, LMP8601-Q1

FEATURES

DESCRIPTION

The LMP8601 and LMP8601Q are fixed 20x gain

•

Unless Otherwise Noted, Typical Values at T_A

= 25°C, V_S= 5.0V, Gain = 20x

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.

LMP8601Q Available in Automotive AEC-

Q100 Grade 1 Qualified Version

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 Application Information.
