SM5865AM

SM5865AM NIPPON PRECISION CIRCUITS INC. D/A Converter 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 application 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-accuracy analog signals, with appropriate lowpass filtering of the output signal. A single SM5865AM IC can be used in combination with an 8-times oversampling digital filter for conversion for a single audio channel. lim Package 0.8 FEATURES s s s s pre s s s s Single-channel D/A converter built-in High performance (120 dB signal-to-noise ratio) (0.001% total harmonic distortion and noise) (110 dB dynamic range) Σ∆ D/A converter 3rd-order noise shaper 23-level quantizer Input data format 20 or 24-bit word length MSB first, right-justified format 8 or 4 times oversampling at fs = 32/44.1/48/ 88.2/96/192 kHz System clock frequency 128/192/256/384/512/768 fs Single 5 V operating supply voltage 24-pin SSOP package Molybdenum-gate CMOS process 5.40 0.20 7.80 0.30 ORDERING INFORMATION Device 0.10 0.10 +0.20 1.90− 0.10 0.36 0.10 0.10 1.80 SM5865AM 24-pin SSOP in...
