The AD5592R/AD5592R-1 integrates 8 individually configured 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 pins are configured as analog outputs, they are driven by a 12-bit DAC. The DAC outputs range from 0 V to VREF, or 0 V to 2 x VREF. When the I/Ox pins are configured as analog inputs, they are connected to the 12-bit ADC via 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. Write/read operations are performed via the Serial Peripheral Interface (SPI) to access GPIO write data registers or GPIO read configuration registers, respectively, to position or read back GPIO pin state.
The AD5592R/AD5592R-1 integrates a 2.5 V, 25 ppm/°C reference (off by default) and a temperature indicator (indicating chip temperature). The temperature value readback is part of the ADC reading sequence.
The AD5592R/AD5592R-1 is available in 16-pin, 2 mm x 2 mm WLCSP, and 16-pin 3 mm x 3 mm LFCSP packages. AD5592R/AD5592R-1 operating temperature range from -40°C to +105°C.
