LC78816MB, 78816MC
16-Bit D/A Converter for Use in
Digital Audio Products
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

D/A Conversion Technique Used in the LC78816MB and 78816MC
Figure 1 D/A Conversion Technique Used in the LC78816MB and 78816MC
Vref pins (See Figure 1.)
The Vref pins that provide the reference voltages for the resistor string are normally set at VrefH = 5 V and VrefL = 0 V.
Also, a capacitor of about 47 µF should be connected between REFH and AGND, and another between REFL and
AGND. As a result of the built-in resistors RH and RL, the maximum output amplitude of the LC78816MB and
78816MC is in a range of 0.5 V (min) to 3.8 V (max) (3.3 Vp-p) for 0 dB playback.
