LMP8480 / LMP8481

Precision 76V High-Side Current Sense Amplifiers with Voltage Output

General Description

Features

The LMP8480 and LMP8481 are precision high-side current

sense amplifiers that amplify a small differential voltage de-

veloped across a current sense resistor in the presence of

high input common-mode voltages.

Typical values, T_A= 25°C

These amplifiers are designed for bidirectional (LMP8481) or

unidirectional (LMP8480) current applications and will accept

input signals with common-mode voltage range from 4V to

76V with a bandwidth of 270 kHz.

Since the operating power supply range overlaps the input

common mode voltage range, the LMP848x can be powered

by the same voltage that is being monitored. This benefit

eliminates the need for an intermediate supply voltage to be

routed to the point of load where the current is being moni-

tored, resulting in reduced component count and board

space.

-40 to +125°C

The LMP848x family consists of fixed gains of 20, 50, 60 and

100 for applications that demand high accuracy over temper-

ature. The low input offset voltage allows the use of smaller

sense resistors without sacrificing system error.

Applications

High-side current sense

●

The wide operating temperature range of -40C to 125C makes

the LMP848x an ideal choice for automotive, telecommuni-

cations, industrial, and consumer applications.

Vehicle current measurement

Telecommunications

Motor controls

The LMP8480 and LMP8481 are pin for pin replacements for

the MAX4080 and MAX4081, offering improved offset volt-

age, wider reference adjust range and higher output drive

capabilities.

Laser or LED Drivers

Energy Management

Solar Panel Monitoring

The LMP8480 and LMP8481 are available in a 8-pin MSOP

package and the LMP8481 is also available in a 8–pad LLP.
