Overview

The LC78816MB and 78816MC are 16-bit CMOS D/A

converters for use in digital audio products. They employ

a dynamic level shift conversion technique that combines

a resistor string (for the upper 9 bits), PWM (for the

middle 3 bits), and level shifting (for the lower 4 bits).

Features

• Two’s complement data format

• Two D/A converter channels built in (in-phase outputs)

• Maximum conversion frequency of 400 kHz (support for

8 times oversampling)

• Built-in output op amps

• No deglitching circuit required

• Si gate CMOS process (low power consumption)

• 5 V single-voltage power supply

• Low voltage (3.5 V) operation possible
