AD5593R

Data Sheet AD5593R 8-Channel, 12-Bit, Configurable ADC/DAC with On-Chip Reference, I2C Interface FEATURES ► 8-channel, configurable ADC/DAC/GPIO ► Configurable as any combination of ► 8 12-bit DAC channels ► 8 12-bit ADC channels ► 8 general-purpose I/O pins ► Integrated temperature sensor ► 16-lead TSSOP and LFCSP and 16-ball WLCSP packages ► I2C interface APPLICATIONS ► Control and monitoring ► General-purpose analog and digital I/O FUNCTIONAL BLOCK DIAGRAM GENERAL DESCRIPTION The AD5593R has eight input/output (I/O) pins, which can be independently configured as digital-to-analog converter (DAC) outputs, analog-to-digital converter (ADC) inputs, digital outputs, or digital inputs. When an I/O pin is configured as an analog output, it is driven by a 12-bit DAC. The output range of the DAC is 0 V to VREF or 0 V to 2 × VREF. When an I/O pin is configured as an analog input, it is connected to a 12-bit ADC via an analog multiplexer. The input range of the ADC is 0 V to VREF or 0 V to 2 × VREF. The I/O pins can also be configured to be general-purpose, digital input or output (GPIO) pins. The state of the GPIO pins can be set or read back by accessing the GPIO write data register and GPIO read configuration registers, respectively, via an I2C write or read operation. The AD5593R has an integrated 2.5 V, 20 ppm/°C reference that is turned off by default and an integrated temperature indicator that gives an indication of the die temperature. The temperature value is read back...
