SGM71632H4

The SGM71632H4 stands as a highly precise, 4-channel, 16-bit digital-to-analog converter (DAC). It functions across a supply voltage range of ±5V to ±18V when in bipolar output mode, and within ±5V to 24V/-12V in unipolar mode. Through utilization of a 5V reference, the SGM71632H4 can be conveniently configured to produce outputs such as ±10V, ±5V, 0V to 20V, or 0V to 10V. Noteworthy attributes of the SGM71632H4 encompass its provision of 16-bit monotonic behavior, exceptional integral nonlinearity (INL) error control within ±1LSB, minimal glitch and noise characteristics throughout an operational temperature span ranging from -40℃ to +125℃. The manufacturing process includes precision trimming to minimize zero and gain errors. Moreover, the SGM71632H4 introduces a user-configurable system- level calibration function that enables the attainment of ±0.125LSB zero error and ±1LSB gain error. 

Embedded within the SGM71632H4 are integrated reference buffers and output buffers. Its key features encompass a standard high-speed 1.8V, 3V, or 5V serial peripheral interface (SPI) capable of functioning at clock frequencies of up to 50MHz for seamless interaction with a DSP or microprocessor. Addressing the four DAC channels and auxiliary registers involves employing four address bits. The device incorporates double-buffered interface logic to enable concurrent updates for all DACs. Introducing an asynchronous load input (nLDAC) that facilitates the transfer of data from the input data register to the DAC latch, the content residing in the DAC latch establishes the resultant output voltage. Furthermore, the asynchronous nRST input serves to reset the output of all four DACs to 0V. The V_MON pin serves as an analog monitoring output that offers multiplexing capabilities for the individual DAC outputs or the AIN pin.
