The SGM5348-12 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 SGM5348-12 also offers daisy-chain operation, where an unlimited number of SGM5348-12s can be updated simultaneously using a single serial interface.
There are two references for the SGM5348-12. One reference input serves channels 1 through 4, while the other reference serves channels 5 through 8. Each reference can be set independently between 0.5V and VCC, providing the widest possible output dynamic range. The SGM5348-12 has a 16-bit input shift register that controls the mode of operation, the power-down condition and the register/output value of the DAC channels. All 8 channels DAC outputs can be updated simultaneously or individually.
The SGM5348-12 is available in Green TSSOP-16 and TQFN-3×3-16L packages. It operates over the extended industrial temperature range of -40℃ to +125℃.
