DESCRIPTION

· The SENIS® SENCS1Dx is a programmable current sensor combining a linear Hall sensor and a coil to enhance measurement bandwidth and signal-to-noise ratio, offering the highest frequency bandwidth in its class.

· It provides an analog output voltage proportional to the magnetic field density, with a transfer characteristic factory-trimmed over temperature and programmable during end-of-line calibration.

· Typically used with a ring-shaped soft ferromagnetic core, recommended to be ferrite or laminated for high bandwidth applications.

FEATURES

· Wide power supply range: 3.3V - 5.5V.

· Selectable measurement ranges: 5 mT to 1 T.

· High-speed AC and DC current sensing: 1 MHz bandwidth, response time <0.5 µs.

· High linearity: down to 0.15% full scale.

· Selectable ratiometric analog output.

· Low noise: 40 µTrms.

· OTP memory: 4 pages for user settings.

· Programmable quiescent reference output: 0-5V.

· Single wire serial interface: Manchester protocol for sensor configuration.

· Operating temperature: -40°C to +150°C.

· Protection circuit: 12V surge, ESD: 4KV.

· Under/Over voltage detection.
