8-Channel, 12-Bit, Configurable ADC/DAC
with On-Chip Reference, SPI Interface
AD5592R
Data Sheet
When an I/Ox 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 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. The state of the GPIO pins can be set or read back
by accessing the GPIO write data register or the GPIO read
configuration register, respectively, via a serial peripheral
interface (SPI) write or read operation.
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 digital input/output pins
Integrated temperature sensor
SPI interface
Available in
16-ball, 2 mm × 2 mm WLCSP
16-lead, 3 mm × 3 mm LFCSP
16-lead TSSOP
The AD5592R/AD5592R-1 have an integrated 2.5 V, 25 ppm/°C
reference, which is turned 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.
APPLICATIONS
Control and monitoring
General-purpose analog and digital inputs/outputs
The AD5592R/AD5592R-1 are available in 16-ball, 2 mm ×
2 mm WLCSP, 16-lead, 3 mm × 3 mm LFCSP, and 16-lead
TSSOP. The AD5592R/AD5592R-1 operate over a temperature
range of −40°C to +105°C.
GENERAL DESCRIPTION
The AD5592R/AD5592R-1 have eight I/Ox pins (I/O0 to I/O7)
that 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/Ox pin is
configured as an analog output, it is driven by a 12-bit DAC.
