ADAC Click Board
ADAC Click Board
Overview
Das ADAC Click Board™ ist ein 8-Kanal-12-Bit-ADC, DAC und GPIO. Das ADAC Click Board™ kommuniziert mit dem Zielmikrocontroller über die I2C-Schnittstelle, wobei zusätzliche Funktionen durch den RST-Pin auf der MikroBUS-Leitung bereitgestellt werden.
Das ADAC Click Board™ ist für den Betrieb mit einer 3,3-V- oder 5-V-Stromversorgung ausgelegt.
The ADAC Click Board™ is an 8-channel 12-bit ADC, DAC and GPIO. It carries the AD5593R configurable ADC/DAC, from Analog Devices. The click is designed to run on either 3.3V or 5V power supply. The ADAC Click Board™ communicates with the target microcontroller over I2C interface, with additional functionality provided by the RST pin on the mikroBUS™ line.
How Does The ADAC Click Board™ Work?
Every channel can be set individually as ADC, DAC, or GPIO. The 12-bit conversion values are readable through I2C.
For resetting the IC, use the Reset pin (RST).
AD5593R IC FEATURES
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 VREF 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 VREF or 0 V to 2 × VREF. The I/O pins can also be configured to be general-purpose, digital input or output (GPIO) pins.
