SGM5351-16
16-Bit, Ultra-Low Glitch,
Voltage-Output Digital-to-Analog Converter
GENERAL DESCRIPTION
FEATURES
The SGM5351-16 is a low power, single channel, 16-bit,
voltage-output DAC. It operates from a 2.7V to 5.5V
supply and the monotonicity is guaranteed by design.
● Power Supply Range: 2.7V to 5.5V
● 16-Bit DAC, Monotonicity Guaranteed by Design
● 6LSB (TYP) Relative Accuracy
● Low Power Operation: 100μA at 2.7V
● Power-On Reset to Zero-Scale
● 10μs (TYP) Settling Time
The SGM5351-16 sets the output range by using an
external reference voltage. It incorporates a power-on
reset circuit that ensures the DAC output powers to 0V
and remains powered up at this level until a valid write
takes place. The SGM5351-16 provides a power-down
mode accessed via the serial interface that reduces the
current consumption of the device to 450nA (TYP) at
5.5V. The SGM5351-16 consumes 0.27mW (TYP) at
2.7V in normal mode, which reduces to less than 1μW
in power‑down mode, the low power consumption in
normal mode is very suitable for portable battery-
operated equipment.
● 3-Wire Serial Interface with Schmitt Trigger Logic
Inputs
● Rail-to-Rail Buffered Voltage-Output Operation
● Binary Code Input
● Power-Down Function
● nSYNC Interrupt Facility
● Available in a Green MSOP-8 Package
APPLICATIONS
The SGM5351-16 uses a 3-wire serial interface which
can be operated at clock rates to 30MHz and is
compatible with standard SPI interface.
Portable Instrumentation
Programmable Attenuators
Process Control
The SGM5351-16 is available in a Green MSOP-8
package. It operates over an ambient temperature
range of -40℃ to +125℃.

OVERSTRESS CAUTION
ABSOLUTE MAXIMUM RATINGS
Stresses beyond those listed in Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to
absolute maximum rating conditions for extended periods
may affect reliability. Functional operation of the device at any
conditions beyond those indicated in the Recommended
Operating Conditions section is not implied.

ESD Susceptibility
ESD SENSITIVITY CAUTION
This integrated circuit can be damaged if ESD protections are
not considered carefully. SGMICRO recommends that all
integrated circuits be handled with appropriate precautions.
Failure to observe proper handling and 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.

into the input shift register on the falling edges of SCLK. After the 24th falling edge of
SCLK, the DAC is updated. If nSYNC is brought high before this edge, the rising edge of
nSYNC acts as an interrupt and the write sequence is ignored by the DAC.

DETAILED DESCRIPTION
DAC Section
nSYNC Interrupt
The SGM5351-16 is a resistor string DAC followed by an
output buffer amplifier. The input code to the SGM5351-16 is
straight binary, so the ideal output voltage can be calculated
based on the following equation:
In a normal write/read sequence, the nSYNC line must be
kept low for at least 24 falling edges of SCLK and the DAC is
updated on the 24th falling edge. However, if nSYNC goes
high before the 24th falling edge, this write/read operation is
invalid and ignored. An example is shown in Figure 5.

× VREF
Power-On Reset
Where:
The SGM5351-16 has a power-on reset circuit, which can
control the output voltage during power-up. On power-up, the
DAC output voltages are 0V.
DIN = Equal decimal code that is loaded to the DAC register,
it’s from 0 to 65535.
Serial Interface
Power-Down Modes
The SGM5351-16 supports four separate modes of operation.
The 3-wire serial interface (nSYNC, SCLK, and DIN/OUT) is
compatible with SPI interface standard. The SGM5351-16
supports 3-wire SPI read and write operation. See Figure 1
for an example of a write sequence, and see Figure 2 for an
example of a read sequence.
The detailed operating mode is shown in Table 1.

Normal operation
The input shift register is 24 bits wide, as shown in Figure 4.
The first 5 bits are unused bits. DB[18] is a write or read
selection bit. These bits are transferred to the DAC register
on the 24th falling edge of SCLK.

NOTE:
1. When in write data mode, DB[18] = 0, DB[17:0] are the data to be written to DAC; when in read data mode, DB[18] = 1,
DB[17:0] are the data to be read out from DAC.
