16-Bit D/A Converter for Use in
Digital Audio Products
Preliminaly
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).
