3. Description of MDSC/MDRC38 Series Digital to Synchro Converters or Digital to Resolver Converters

MDSC/MDRC38 series are the converter that converts the input binary signal into sin and cos signal output. Input signal is compatible with DTL/TTL/CMOS level, the output signal is orthogonal sin and cos signal which can directly drive isolation transformer or SCOTT transformer, then, is converted into arbitrary value of resolver or synchro signal. This series of product continuously tracks the input 12-bit/14-bit/16-bit binary data, and outputs high-precision synchro/resolver signal after conversion, it has higher conversion accuracy and latch function. The product is equipped with power amplification circuit inside it, and its output power can reach 1.3W.
