This single chip converter offers programmable features such as resolution, bandwidth, velocity output scaling and encoder emulation. DataSheet4U.com Resolution programming allows selection of 10, 12, 14, or 16 bit, with accuracies to 1.3 minutes. The parallel digital data and the internal encoder emulation signals (A QUAD B) have independent resolution control. Internal encoder emulation will permit inhibiting (freezing) the parallel digital data without interrupting the A and B outputs. The internal Synthesized Reference section eliminates errors due to quadrature voltage and ensures operation with a rotor-to-stator phase shift of up to 45 degrees. The velocity output (VEL) can be used in place of a tachometer. It has a range of ±4 V relative to analog ground. The velocity scale factor/tracking rate is programmed with a single resistor. This converter provides the...
