16-Bit D/A Converter
Description
Ordering number : EN*4250C
CMOS LSI
LC78816MB, 78816MC
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).
