SGM5348-10
8 Channels, 10-Bit Digital-to-Analog Converter
with Output Operational Amplifier
GENERAL DESCRIPTION
FEATURES
The SGM5348-10 features 8 channels of digital-to-
analog converter (DAC) with output amplifiers. The
output amplifier provides high current drive capability.
The digital data is sent via SPI interface, and cascaded
connections can be used. The SGM5348-10 provides
daisy-chain capability, which can update multiple
SGM5348-10s simultaneously by using a single serial
interface.
● Low Power Consumption (0.5mW/CH)
● Integrating 8 Channels of 10-Bit DAC
● Built-In Rail-to-Rail 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
● 0.1% (TYP) Gain Error for All Channels
● Interface Sees No Quiescent Current when VBUS < VCC
● Power-On Reset: Output Reset to GND
● Serial Data Input: Up to 40MHz Operation
● TTL Compatible Input Logic Level
The SGM5348-10 has two references (one reference
input for channel 1 to channel 4, and the other
reference for channel 5 to channel 8). Each reference
voltage operates independently from a 0.5V to VCC
supply, providing a dynamic range of output as broad
as possible. The SGM5348-10 contains a 16-bit shift
register, which controls the operation mode, the
power-down condition and the register/output value of
the DAC channels. All 8 channels DAC outputs can be
updated simultaneously or separately.
● Power Supply Voltage Range: 2.8V to 5.5V
● Double Reference Voltages Range: 0.5V to VCC
● -40℃ to +125℃ Operating Temperature Range
● Available in a Green TSSOP-16 Package
The SGM5348-10 incorporates a power-on reset circuit
that ensures the DAC outputs power to 0V and remains
0V until a valid write occurs. The SGM5348-10
provides a power-down function that allows each DAC
to be separately powered with three different output
terminations. When all the DAC channels are powered
down, the current consumption of the device reduces to
less than 1.5μW at 3V and less than 3μW at 5V.
