DESCRIPTION
MAS6116 is a stereo volume control for audio
systems, which require high output voltages (AC3).
It has serial interface, which controls two audio
channels.
Simple
serial
interface
allows
microcontroller to control many MAS6116 chips on
the same PCB board. “Clicking” between gain
changes is eliminated by changing gain only when
zero crossing has been detected in the input signal.

GENERAL DESCRIPTION
Main features
MAS6116 is a stereo digital volume control designed for audio systems. The levels of the left and right analog
channels are set by the serial interface. Both channels can be programmed independently. The channel gains can
be programmed from -111.5 dB to +15.5 dB with 0.5 dB resolution. The code for -112 dB (00HEX) activates mute
for maximum attenuation. MAS6116 operates from single +5V supply and accepts analog input signal levels up to
±18V.
MAS6116 has a zero cross detect function that changes the channel gain only when a zero crossing has been
detected in the input signal. This eliminates clicking sounds from the output signal when the gain is changed. The
zero cross detection circuit is also equipped with a timeout function to make sure the gain value is updated even
when there is no input signal.
Channel gains can also be changed instantly without using the zero cross detect function. This can be done with
dedicated instant gain change commands specified in Register Description on page 7. Using this feature to
change channel gains in large increments is not recommended because it may cause large transients in the
output signal. See chapter Changing the gain of the channels and chapter Write operation status register for
further details.
The XMUTE pin in MAS6116 always uses the zero cross detection and timeout functions when entering to or
returning from the MUTE state. This prevents fast transients from occurring in the output signal.
Serial interface
Control information is written into or read back from the internal register via the serial control port. Serial control
port consists of a bi-directional pin for data (DATA), chip select pin (XCS) and control clock (CCLK) and supports
the serial communication protocol. All control instructions require two bytes of data.
To shift the data in CCLK must be pulsed 16 times when XCS is low. The data is shifted into the serial input
register on the rising edges of CCLK pulses. The first 8 bits contain address information. The second byte
contains the control word. XCS must return to high after the second byte. That is, after the 16th CCLK XCS must
be returned to high. See chapter Serial interface timing diagram on page 12.
The same process takes place for reading the information. XCS will remain low for next 16 CCLK pulses. The
data is shifted out on the falling edges of CCLK. When XCS is high, the DATA pin is in high impedance state,
which enables DATA pins of other devices to be connected together.
On the PCB board the same DATA and CCLK lines can be routed to every MAS6116 chip. If the XCS-pin is not
active (low), DATA pin of that chip is in high-impedance state. This allows using a simple PCB board for multichannel audio systems.

GENERAL DESCRIPTION
Operating modes
When power is first applied, power-on reset initializes control registers and sets MAS6116 into mute state,
ignoring the state of the XMUTE pin. The activation of the device requires that XMUTE pin is high and a control
byte with a greater than the default value (00HEX) is written in the gain register. It is possible to return to the mute
state either by setting XMUTE pin low or writing zero (00HEX) to the gain register. Setting the XMUTE pin low will
mute both channels. Setting the XMUTE pin back high will return the channels to previously written gain values.
The zero cross detector function is used when entering and returning from the mute state to prevent large
transients in the output signal (see chapter Changing the gain of the channels).
The device has a special test mode register, which is used only for internal testing of the device. It is strongly
recommended not to change the default value (00HEX) of the test register during normal operation. For device
testing the XMUTE pin is bi-directional. When the test register bit 1 is set to high, XMUTE pin is in output mode. In
the test mode internal signals can be directed to the XMUTE pin. Note: In the test mode both analog outputs are
in mute state and the device will not allow new gain values to be written in the gain registers. An exception to this
is the force latch command specified in table Test Register CR5 Description, which can be used to instantly
change the gain of both channels. This function is intended to be used in the test mode only, and it is
recommended to use the commands specified in Register Description to instantly change the channel gains.
Changing the gain of the channels
When a new gain value is written to the gain register the device will activate the zero crossing detection and delay
generator for the selected channel. MAS6116 will wait until a rising edge of the input signal is detected to change
the gain value. This is done to ensure that no audible clicks are produced to the output signal during the gain
change operation. The zero cross detection circuit has also a timeout delay generator that will force the gain
change. The delay generator generates a typical delay of 22 ms.
If a new gain value is written before the previous write operation has finished, the previously written value will be
overwritten and will not be set to the output. If it is desired that each gain value is set to the output, it is
recommended to read the status bit from the write operation status register (CR6) or wait for at least 30 ms before
the next gain change instruction.
Both channels can be programmed independently with separate commands. In this case the gain values will be
set to the output in the order of writing. Both channels can also be programmed to the same value by writing only
one instruction (see the Register Description on page 7).
Note: Due to the input signal dependency of the zero cross detection circuits the order of the gain changes may
differ from the order of writing to the registers if the input signals to the channels are different. This applies to all
instructions that use the zero cross detection and timeout functions, i.e. instructions that are not labeled as
“instant” in the register description.
The new gain value can be set instantly to the output by using the instant gain change function. By using this
command function the gain is set to the output instantly after the write operation has finished, without waiting a
zero cross to occur in the input signal or a delay to pass. The gains can be set independently to both channels
using different commands, or both channels can be set to the same gain value by using a single command. Using
the instant gain change function to change the gain value in larger than 0.5 dB steps may produce audible clicks
to the output signal.

GENERAL DESCRIPTION
Peak level detection
MAS6116 has a 8-bit digital-to-analog converter (DAC) used to monitor the peak level of the output signal. The
reference value is programmed using the serial interface and the same reference value is used for both channels.
The reference value V REF can be calculated using the following formula.
VREF = (0.0036 + 0.0145 · CODE) · AVCC
where CODE is the decimal value of the control byte (0...255) and AVCC is the analog supply voltage of the
MAS6116 device. With nominal analog supply voltage of 5V the reference value is
VREF = 18mV + 72.5mV · CODE
When a positive peak signal level at the output exceeds the V REF value, bits 0 and 1 of the status register are
set (see register description). When set, the register contents will remain high until the value of the status register
has been read.
Write operation status register
MAS6116 features a status register that can be used to determine if the channel registers are ready to accept
new gain values. The status register bits 0 and 1 are set high at the start of a gain write operation, and are set
back low when the new gain value has been set to the output. This happens when a positive zero crossing is
detected in the input signal or the timeout delay has passed.
It is allowed to write a new gain value to a channel that is busy (i.e. waiting for a zero cross in the input signal).
The new value will overwrite the previous one and the timeout delay will be reset. This means that the previously
written gain value will not be set to the channel gain registers. To prevent this from happening it is recommended
to read the write operation status register prior to setting a new gain value to determine if the write operation can
be safely executed.

POWER-ON RESET
MAS6116 has a Power-On Reset circuit (POR) that ensures that the circuit is set to a known state when power is
applied. The device can be activated as described in chapter Operating modes after the POR delay has passed.
In addition MAS6116 has a supply voltage monitoring circuit, that monitors the digital supply voltage (DVCC) level.
If the digital supply voltage drops below the specified level, the circuit is set to RESET state. The voltage
monitoring circuit is functional only when sufficient analog supply voltage (AVCC) is present.

APPLICATION INFORMATION
Application Note 3 – Single supply voltage usage
Single supply voltage circuit below is based on signal AC coupling and biasing output opamp in the middle point of
supply voltages. Note that only right channel circuit is presented. The left channel circuit would be exactly the
same. The component values have been chosen to limit overall lower corner frequency to about 10 Hz.

Application Note 4 – Lower supply voltage MCU communication example 1
If the serial control interface is driven from MCU which operates from lower supply voltage than MAS6116 which is
using higher 5V voltage supply there is level shifting needed for keeping the digital signal levels proper in the
communication. The bi-directional DATA line requires additionally level shifting in both directions. Figure below
shows an example of serial interface level shifting between 3V and 5V voltage supplies. In this example level
shifters with output enable function are used. The output enable function is used to disable level shifter output
when data direction changes in the bi-directional data line of MAS6116.
