Overview
The LC8390M combines two-channel D/A and A/D converters in a single chip

Features
• A/D Converter Block
   — Quadratic ∆Σ modulation
   — 16-bits resolution
   — Built-in aliasing noise prevention digital filter
   — A/D converters for two channels built in (synchronized input when standard audio output is used)
   — S/N = 80 dB, THD + N = 0.025% (typical, A compensation filter used)
   — Digital output: MSB first, forward packed, bit clock rates of 32, 48, and 64 Fs
   — External integrator used.
• D/A Converter Block
   — 16× oversampling quadratic noise shaper + PWM
   — 16-bits resolution
   — D/A converters for two channels built in (synchronized output)
   — S/N = 85 dB, THD + N = 0.03% (typical, A compensation filter used)
   — Digital input: MSB first, backward packed, bit clock rates of 32, 48, and 64 Fs
   — Digital oversampling filters are not built in.
• Built-in double-buffering serial I/O circuits. (These circuits support both standard audio I/O and I/O with arbitrary timing.)
• Sampling frequencies of 48, 44.1, and 32 kHz
• Master clock: 512 Fs (24.576 MHz when fs = 48 kHz) or 384 Fs
   Notes: Only the A/D converters operate when 384 Fs is selected as the master clock. The D/A converters do not operate in this mode. Since the analog I/F and analog power supply pins are more susceptible to damage from static electricity than the other pins, extra care is required.
   Analog I/F pins: DZOUTL, ADL2, ADLVSS, ADLVDD, ADL3, DZOUTR, ADR2, ADRVSS, ADRVDD, ADR3, DALVSS, PWML, DALVDD, DARVSS, PWMR, DARVDD
• Package: 30-pin MFP
• Power supply: 5 V, single voltage, CMOS
