Linear Technology LT2940CDD#PBF
- Part Number:
- LT2940CDD#PBF
- Manufacturer:
- Linear Technology
- Ventron No:
- 3265065-LT2940CDD#PBF
- Description:
- IC CURRENT/POWER MONITOR 12DFN
- Datasheet:
- LT2940CDD#PBF
Description
The LT2940 is a power and current monitor that measures high side current and differential voltage, multiplies them, and outputs a current proportional to instantaneous power. It features four-quadrant power measurement, ±5% power measurement accuracy, and a high side sense range of 4V to 80V (100V max). The LT2940 also provides current mode power and current outputs with an output bandwidth exceeding 500kHz, ±3% current measurement accuracy, and a supply range of 6V to 80V (100V max). Additionally, it has inverting and noninverting open-collector comparator outputs.
