ADAF1080BCPZ

ADAF1080 is a single-axis, high-precision, magnetic-field sensor with integrated signal conditioning. The device incorporates an anisotropic magnetoresistive (AMR) sensor with an integrated signal-conditioning amplifier, electrical-offset cancellation capabilities, integrated diagnostics, and an analogue-to-digital converter (ADC) driver for precise measurement of magnetic fields up to ±8mT. It consists of two die within one package, an AMR sensor, and an application-specific IC (ASIC). The ADAF1080 provides a precision amplified output signal that is proportional to the magnetic field strength along the sensitive axis of the sensor. Typical applications are isolated and contactless current sensing, handheld current clamp meters, motor control current sense, AC and DC power applications, precision magnetic field sensing applications, precision linear encoders, low-noise, precision magnetometers.
