The DSC-11524 is a versatile multiplying Digital-to-Synchro/R
esolver converter. The digital input represents an angle, and the output is pin programmable for either Resolver, SIN/COS, or three-line synchro type output. The reference input will accept any waveform, even a sawtooth for CRT drive. Because the reference is DC coupled to the output, the DSC-11524 can be used in many configurations, such as: a Digital-to-Synchro/R
esolver converter using a sinusoidal reference as an input; a Digital-to-SIN/COS DC converter using a DC reference; a polar-to-rectangular converter using a reference input proportional to the radius vector; a rotating cartwheel sweep generator for PPI displays using a sawtooth reference. Packaged in a 36-pin DDIP, the DSC-11524 is a complete D/S and D/R converter in one hybrid module. Hybrid technology results in low weight, low power consumption, very high reliability, and a wide operating temperature range. The DSC-11524 circuit design allows for higher accuracy and reduces the output scale factor variation so that the output can drive displays directly. The output line-to-line voltage can be scaled by external resistors. Other features include high AC and DC common mode rejection at the reference input, and output short circuit protection.
