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

Function and Operational Description
Channel 1 output pin (left channel)
Reference voltage high level pin
Normally connected to AGND through a capacitor.
Reference voltage high level input pin
Analog system power supply voltage pin
LR clock and word clock input pin
Used to generate the internal signal that latches the digital audio data (DATAL and DATAR).
Digital audio data input pin
Data is input from the MSB bit serially.
When FSEL is low, channel 1 data is input.
When FSEL is high, channel 1 and channel 2 data are input using time division.
Digital audio data input pin
Data is input from the MSB bit serially.
When FSEL is low, channel 2 data is input.
When FSEL is high, functions as the interface switching pin.
Bit clock input pin
This is the clock for reading in digital audio data bit serially. Also functions as the IC’s system clock when SYSCLK is
fixed low or high.
System clock input pin
This is the system clock that drives the IC. However, in certain modes it is used as the interface switching pin.
(See the timing charts.)
Digital system power supply voltage pin
Output pin for IC testing
When low, digital audio data is input simultaneously from the DATAL and DATAR pins.
When high, digital audio data is input from the DATAL pin in time division mode.
Interface switching pins. (See the timing charts.)
Digital system ground pin
Reference voltage low level pin.
Normally connected to AGND through a capacitor.
Analog system ground pin
Reference voltage low level input pin
No connection
Channel 2 output pin (right channel)
