SGM5347-8
8 Channels, 8-Bit Digital-to-Analog Converter
with Output Operational Amplifier
GENERAL DESCRIPTION
FEATURES
The SGM5347-8 features 8 channels of 8-bit digital-to-
analog converter (DAC) with output amplifiers. The
output amplifier provides high current drive capability.
The digital data is input via a serial link bus. Only three
control lines are required, and cascaded connections
can be used. The SGM5347-8 provides daisy-chain
capability, which can update multiple SGM5347-8s
simultaneously by using a single serial interface.
● Low Power Consumption (0.5mW/CH)
● Integrating 8 Channels of 8-Bit DAC
● Build-In Analog Output Amplifier:
Sink/Source Current with Short Current Control
● Daisy-Chain Operation
● 8 Channels Outputs Update Simultaneously
● Independent Channel Power-Down Function
0.6μA (TYP) ICC for Power-Down Mode
● The Range of D/A Conversion can be Independently
Set by Separating the Power Supply for MCU Interface
and Operational Amplifier and the Power Supply for
DAC
The SGM5347-8 is available in Green SOIC-16 and
TSSOP-16 packages. It operates over an ambient
temperature range of -40℃ to +125℃.
● Capable of Being Controlled Directly by a 3V MCU
● Power-On Reset: Output Reset to GND
● Serial Data Input: Up to 2.5MHz Operation
● Power Supply Voltage Range: 2.8V to 5.5V
● Available in Green SOIC-16 and TSSOP-16

ESD Susceptibility
This integrated circuit can be damaged if ESD protections are
not considered carefully. SGMICRO recommends that all
integrated circuits be handled with appropriate precautions.
Failureto observe proper handlingand installation procedures
can cause damage. ESD damage can range from subtle
performance degradation tocomplete device failure. Precision
integrated circuits may be more susceptible to damage
because even small parametric changes could cause the
device not to meet the published specifications.

•
SGM5347-8 has a 12-bit shift register for chip control.
It is necessary to set the data as following configuration to a 12-bit shift register.
The data consists of 12 bits: a 4-bit address selection and an 8-bit DAC control signal.

BITS
BIT NAME
DESCRIPTION
DB[7:4]
N/A
1 = Reset internal circuit other than the shift register. Will be automatically cleared to 0 after writing a 1. Since
the reset doesn't hold, the next frame can be used for command. For example, at the first frame, the RST bit is
written so that all DAC outputs reset to 0 at rising edge of the LD signal. The second frame can be a data
writing command, but the DAC outputs won't be changed from 0 until writing of the data takes effect by the LD
signal of the second frame
DB[3]
RST
1 = The rising edge of LD signal updates data in DIN register of all 8 channels to the corresponding data
registers. The bit is then automatically cleared to 0
0 = The rising edge of LD signal loads the data in shift register to DIN and DATA
1 = The rising edge of LD signal only loads the data in shift register to DIN register indicated by ADDR but does
not update the data register. LD will update all 8 channels when writing to channel 8
0 = The pull-down resistance is around 300kΩ
DB[2]
DB[1]
UPDATE
SYNC
DB[0]
3K_PULL
1 = Enable the 3kΩ pull-down resistors for all the 8 channels. The pull-down resistors are only enabled in
power-down mode
Example one of a simultaneous update:
1. Write 0x02 to CONTROL register.
2. Write data to channel 1, to channel 2 … to channel 7.
3. Writing data to channel 8 causes all the 8 channels to update at the same time. Then the following writings are still
simultaneously updated.
4. Write 0x00 to CONTROL register to exit simultaneous update mode.
Example two of a simultaneous update:
1. Write 0x02 to CONTROL register.
2. Write data to channel 1, to channel 2 … to channel 7.
3. Write 0x06 to CONTROL register to update all the 8 channels. Then the following writings are still simultaneously updated.
4. Write 0x00 to CONTROL register to exit simultaneous update mode.
