Power Monitors

Analog Devices’ power monitoring ICs provide an integrated solution for digital current and voltage measurement via an on-chip, 12-bit analog-to-digital converter (ADC). Leveraging ADI’s precision analog design techniques, ADI’s products are twice as precise as competing devices, offering best-in-class accuracy (<±0.8%). The power monitors complete the industry’s only monitor and sequencer family to deliver <±1% accuracy for 2 to 12 supplies.
