1 / 17 page  SM5865AM NIPPON PRECISION CIRCUITS—1 NIPPON PRECISION CIRCUITS INC. D/A Converter OVERVIEW The SM5865AM is a 24-bit input D/A converter for high-quality digital audio equipment. It comprises newly developed DEM (dynamic element matching) circuits, 3rd-order Σ∆ noise shaper and 23-level quantizer to control wide-band residual quantization noise in the signal band, making it ideal for applica- tion with high-frequency sampling formats. Also, the order of the required final-stage analog lowpass filter can be reduced, compared to filters for available devices, enhancing output tone quality. The output stage employs complementary outputs for high-accu- racy analog signals, with appropriate lowpass filter- ing of the output signal. A single SM5865AM IC can be used in combination with an 8-times oversampling digital filter for con- version for a single audio channel.
