AD74115H/AD74115 Input and Output Devices
Analog Devices' AD74115H and AD74115 are single-channel, software-configurable input/output devices
ADI's AD74115H and AD74115 are single-channel, software-configurable input/output devices for industrial control applications. They provide a wide range of use cases integrated on a single chip, including analog output, analog input, digital output, digital input, resistance temperature detector (RTD), and thermocouple measurement capability. The AD74115H also has an integrated HART modem. A serial peripheral interface (SPI) handles all communications to the device, including communications with the HART modem. The digital inputs/outputs can be accessed via the SPI or the general-purpose input and output (GPIO) pins to support higher-speed data rates.
The devices feature a 16-bit, Σ-Δ analog-to-digital converter (ADC) and a 14-bit digital-to-analog converter (DAC). They contain a high accuracy 2.5 V on-chip reference that can be used as the DAC and ADC reference.
Power and isolation can be provided using the ADP1034 companion product. When using the ADP1034 and AD74115H or AD74115 together, programmable power control (PPC) is available on the positive analog supply, AVDD, which allows for an optimized power solution in the end application. An on-chip charge pump can be enabled if unipolar capability is required.
The EVAL-AD74115H-ARDZ and EVAL-AD74115-ARDZ are fully featured evaluation boards that can be used to evaluate the features of the AD74115H and AD74115, respectively, in a full system solution where power and isolation are provided by the ADP1034. The AD74115H and AD74115 are single-channel, software-configurable input and output devices. The devices have functionality for analog output, analog input, digital input, digital output, and 2-wire, 3-wire, and 4-wire RTD measurements integrated into a single-chip solution with a compatible SPI.
