The AD5592R/AD5592R-1 integrates eight I/Ox pins (I/O0 to I/O7) that can be individually configured as digital-to-analog converter (DAC) outputs, analog-to-digital converter (ADC) inputs, digital outputs, or digital inputs. . When the I/Ox pin is configured as an analog output, it is driven by a 12-bit DAC. The DAC output range is 0 V to VREF, or 0 V to 2 x VREF. When the I/Ox pin is configured as an analog input, it is connected to a 12-bit ADC through an analog multiplexer. The ADC input range is 0 V to VREF, or 0 V to 2 x VREF. The ADC has a total throughput rate of 400 kSPS. The I/Ox pins can also be configured as digital, general purpose input or output (GPIO) pins. The GPIO write data register or the GPIO read configuration register can be accessed by the serial peripheral interface (SPI) to read or read the GPIO pin status.

The AD5592R/AD5592R-1 integrates a 2.5 V, 25 ppm/°C reference (default off) and a temperature indicator (indicating chip temperature). The temperature value is read back as part of the ADC read sequence.

The circuit shown in Figure 2 is a multi-channel, flexible analog output solution that uses only two analog components to meet multi-channel I/O cards, programmable logic controllers (PLCs), and distributed control systems (DCS). Most of the requirements of the application. Quad, 16-bit nanoDAC+AD5686R with rail-to-rail buffered output for use with four industrial current/voltage output drivers, the AD5750-2, provides all typical current and voltage output ranges, 16-bit resolution with no missing codes, 0.05 % linearity and output error less than 0.1%.
