Description

VMIC VMIVME-4116 8-channel 16-bit Digital-to-Analog Converter Board. Simple Type: Analog Output Module The VMIVME-4116 Digital-to-Analog Converter (DAC) Board performs digital-to-analog conversion on 16-bit positive true offset binary or two’s complement coded words, with an analog output range of -10 to +10 V. This provides for a resolution of 305 µV for each digital input of 1 LSB change. The buffered output voltage settles to within 1/2 LSB in 10 µs. The DAC offers a Digital-to-Analog Integrated Circuit (IC) per channel. A Control and Status Register (CSR) is loaded by the processor and this register controls the functioning of the board. The CSR can be read by the processor at any time. The VMIVME-4116 board functional block diagram is shown in Figure 1. Each of the eight DACs is preceded by double-buffered data latches. The data latches allow versatility in the way the DAC analog output may be updated.There are three methods by which new data can be converted by a DAC. Each method is enabled/disabled by on-board jumpers and is further controlled by a CSR that must be loaded by the user Download the datasheet (PDF)
