Use this electronics calculation for a first-pass component, converter, signal, motor, or sensor estimate when the stated operating conditions and units match the device data.

X Microtesla

Required number input.

Y Microtesla

Required number input.

Calculate horizontal magnetic heading from leveled, calibrated magnetometer X/Y readings with atan2(Y,X), normalized to 0–360 degrees; declination is excluded. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Heading (°) (°)

The resulting heading (°) returned as a number.

• Magnetic-field and heading results depend on axis alignment, calibration, hard- and soft-iron distortion, local inclination, temperature, nearby current, sensor saturation, and tilt compensation. A field magnitude alone does not provide a reliable compass heading.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Check the result against the current datasheet and worst-case operating corners, then verify the circuit or measurement with simulation and bench testing where failure matters.

• Finite-Gain Closed-Loop Error

  Calculate feedback closed-loop gain A/(1+Aβ) and percent error relative to ideal 1/β. Assumes negative feedback with positive real open-loop gain and feedback factor; frequency dependence is excluded.

• Memory Bandwidth

  Calculate theoretical aggregate bandwidth from transfers per second, bytes per transfer, and active channels. Output is decimal GB/s (10⁹ bytes/s); protocol overhead and idle cycles are excluded.

• ADC LSB Voltage

  Calculate one ideal ADC code width as full-scale input span divided by 2^N. Full-scale span is the high-to-low range, not necessarily the reference voltage for every ADC topology.
