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

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

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,

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 as part of an ADC read sequence.

The AD5593R is available in 16-lead TSSOP and LFCSP, as well

as a 16-ball WLCSP, and operates over a temperature range of

−40°C to +105°C.
