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 V
REF
or 0 V to 2 × V
REF
. 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
V
REF
or 0 V to 2 × V
REF
. 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 I
2
C 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 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.
