LC78835K, 78835KM
18 Bits Digital Filter and D/A Converter
for Digital Audio
Overview
The LC78835K and 78835KM are 18-bit digital-to-analog
D/A converter CMOS ICs with an on-chip eight-times
oversampling digital filter. The LC78835 and the
LC78835M are pin compatible.
Features
• Digital filter
— 8 fs oversampling filter: 3-stage finite-impulse-
response (FIR) filter design (43rd-, 11th-, and third-
orders)
— De-emphasis filter: Supports fs = 32 kHz, 44.1 kHz,
or 48 kHz
— Soft mute
— Noise shaper
— Supports double-rate sampling
• D/A converter
— Dynamic level-shifting 18-bit digital-to-analog
converter
— On-chip 2-channel D/A converter (with
corresponding output)
— On-chip output op-amp
— Supports 384 fs, 392 fs, 448 fs, or 512 fs system
clock
— Single 5 V supply
— Permits low-voltage operation (3.5 V)
— Low-power silicon-gate CMOS process
