Page 13: 10-Bit Digital-To-Analog Converter (Dac)
UM0240 10-bit digital-to-analog converter (DAC) 10-bit digital-to-analog converter (DAC) The Industrial Communication Board embeds a 10(12)-bit buffered voltage-output DAC implemented by the AD5317 (AD5327) converter from Analog Devices. The IC provides four buffered rail-to-rail outputs, in the range 0 ÷ Vcc, with a slew rate of 0.7 V/µs. The DAC is controlled by the Microcontroller (PC2, PC3, PC4) through a 3-wires serial interface and is compatible with SPI, QSPI, MICROWIRE and DSP interface standards. -

Page 19: In-Circuit Communication
Power supply As described in Section 2: Power supply, the ST Industrial Communication Board can take is power supply from different sources. If an external dedicated power supply is selected, it must be in the 5V ÷ 35V range. Taking into account that the board has a power consumption in steady state of approximately 50mW, a value of 500mW is suggested. -
