Part Description

The LMP8480 and LMP8481 are precision high-side current sense amplifiers that amplify a small differential voltage developed across a current sense resistor in the presence of high input common-mode voltages. These amplifiers are designed for bidirectional (LMP8481) or unidirectional (LMP8480) current applications and accept input signals with common-mode voltage range from 4 V to 76 V with a bandwidth of 270 kHz. Because 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 monitored, resulting in reduced component count and board space. The LMP848x family consists of fixed gains of 20, 60, and 100 for applications that demand high accuracy over temperature. The low-input offset voltage allows the use of smaller sense resistors without sacrificing system error. The wide operating temperature range of –40°C to 125°C makes the LMP848x an ideal choice for automotive, telecommunications, industrial, and consumer applications. The LMP8480 and LMP8481 are pin-for-pin replacements for the MAX4080 and MAX4081, offering improved offset voltage, wider reference adjust range and higher output drive capabilities. The LMP8480 and LMP8481 are available in a 8-pin VSSOP package.
