class adi.ad5592r.ad5592r(uri='', device_name='')

Bases: context_manager

AD5592R and AD5593R SPI / I2C interface, 8-channel, 12-bit Confiburable ADC/DAC, digital GPIO

Analog I/O pins are configured in the device tree and can be ADC, DAC, or both. Channel attributes are as follows, where X corresponds to device channel number:

voltageX_adc.raw: Raw 12-bit ADC code. read only for ADC channels

voltageX_adc.scale: ADC scale, millivolts per lsb

voltageX_adc.scale_available: Available scales, corresponding to Vref*1, Vref*2

voltageX(): Returns ADC reading in millivolts (read only)

voltageX_dac.raw: Raw 12-bit DAC code. read/write for DAC channels

voltageX_dac.scale: ADC scale, millivolts per lsb

voltageX_dac.scale_available: Available scales (corresponding to 1X/2X gain)

voltageX(1234.5): Sets/Returns ADC reading in millivolts

temp.raw: Temperature raw value

temp.scale: Temperature scale value

temp.offset Temperature offset value

temp(): Returns temperature in degrees Celsius

The number of individual channels is based on the hardware configuration of the device. The are individually accessed as properties like so:

dev = adi.ad5592r(uri="ip:analog")
dev.dac_0.raw = 10
dev.dac_1.raw = 30
data = dev.adc_0.raw
print(data)
temp_c = (dev.temp_0.raw + dev.temp_0.offset) * dev.temp_0.scale
print(temp_c)
