Allegro is claiming a record for its latest Hall-effect position sensor IC, describing it as “the smallest sine/cosine 3D sensor currently available in the market”. Called A33230, it comes in 3 x 2.9 ...

This approach works because sine and cosine are the building blocks of all other trigonometric functions. For example, to simplify tan θ · csc θ, convert both functions: (sin θ/cos θ) · (1 ...

2. The 1-MHz sine and –cosine outputs of the generator (channels 3 and 4) result from the 100-MHz square-wave input (channel 1). Resistor-divider circuits reduce the amplitude from rail-to rail ...

External CORDIC calculation can be used to turn the device into an angular sensor, extract angular information when the two channels are used to provide sine and cosine of the applied magnetic field. ...

Strategy 1: Convert everything to Sine and Cosine When faced with a complex trigonometric expression, your first move should be converting all functions to sine and cosine.
