Overview
Description
The RAA788000 is a low-power, power-line current sensor for contactless AC current measurements in the range of 2A to 5000A. The device consists of an on-chip Rogowski coil, a buffer amplifier, and a signal amplifier.
From an alternating power-line current, the magnetic flux flows through the on-chip coil, generating an electromotive force (EMF) that is amplified and filtered by a signal amplifier.
The amplifier output is typically fed into an analog-to-digital converter with a subsequent signal processor that calculates the current magnitude.
The RAA788000 operates from a single 2.7V to 3.6V supply. The device is available in a small 16 Ld TSSOP package and has an operation specified for the temperature range from -40°C to +105°C.
The RAA788000 is available in a 16 Ld thin shrink small outline package (TSSOP).
