The features that make the LMP8480 and LMP8481 family unique are it is capable of measuring current in the presence of a CMV of 4.0 V to 76 V and it can do so while being powered by the same common mode voltage. Unlike most other Current Sense Amplifiers (CSAs), which need to be powered by a lower supply like 5 V, 12 V or 18 V, this family has a very wide supply voltage range of 4.5 V to 76 V, this saves on the cost of an additional regulator. Another feature is the low input offset voltage of 90 µV (typ) or 265 µV (max) at room temperature. This low input offset voltage increases the accuracy of the system and allows the use of a smaller shunt. There are CSAs on the market with lower Vos, but they usually sacrifice bandwidth (BW) to get the low Vos. The LMP8480/81 family has a low Vos and a BW of 270 kHz which allows it to be used in applications requiring wider BW to maintain waveform fidelity. Some of the other features include, a buffered voltage output to enable driving lower impedance loads, a high output current drive capability, and the availability of four gain options of 20, 50, 60, and 100 V/V.
