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.
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.
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.
The SGM5348-10 is available in a Green TSSOP-16 package. It operates over the extended industrial temperature range of -40℃ to +125℃.
