LC8390M

16-Bits A/D and D/A Converters

for Digital Audio Systems

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
