Overview

The LC78836M is a 16-bit CMOS D/A converter that includes 8×oversampling filters on chip. It is pin compatible with the LC78835M and LC78835KM.

Functions and Features

Digital Filter Block

•8×oversampling filters: Three FIR filter stages (33rd order, 13th-order, and ninth-order filters)

• De-emphasis filter: Support for 32 kHz, 44.1 kHz, and 48 kHz Fs frequencies

• Soft muting

• Noise shaper

• Supports double-speed operation

D/A Converter Block

• 16-bit dynamic level shifting D/A conversion

• Two D/A converter channels on a single chip (synchronous outputs)

• On-chip output operational amplifiers

• System clock: Supports 384 fs, 392 fs, 448 fs, and 512 fs clocks

• Single 5 V power supply

• Low-voltage operation (3 V) also possible

• Si-gate CMOS process for low power dissipation
