Analog Devices Inc. AD5593R Configurable ADC/DAC
Analog Devices Inc. AD5593R Configurable ADC/DACs with On-chip Reference, I²C Interface feature eight I/O pins that designers can independently configure as DAC outputs, ADC inputs, digital outputs, or digital inputs. When an I/O pin is configured as an analog output, the devices are driven by a 12-bit DAC. The output range of the DACs are 0V to VREF or 0V to 2 × VREF. When an I/O pin is configured as an analog input, the devices are connected to a 12-bit ADC via an analog multiplexer. The input range of the ADCs are 0V to VREF or 0V to 2 × VREF. Designers can also configure the I/O pins to be general purpose, digital input or output (GPIO) pins. By accessing the GPIO registers via an I²C write or read operation, the state of the GPIO pins can be set or read back.
AD5593R provides an integrated 2.5V, 20 ppm/°C reference that is off by default and an integrated temperature indicator which gives an indication of the die temperature. The temperature value is read back as part of an ADC read sequence. Operating over a temperature range of −40°C to +105°C, the AD5593R 8-channel, 12-Bit, configurable ADC/DAC is ideal for control & monitoring as well as general purpose analog & digital I/O applications.
