The AD74115 is a single-channel, software-configurable, input and output device for industrial control applications. The AD74115 provides a wide range of use cases, integrated on a single chip. These use cases include analog output, analog input, digital output, digital input, resistance temperature detector (RTD), and thermocouple measurement capability. A serial peripheral interface (SPI) is used to handle all communications to the device. The digital input and digital outputs can be accessed via the SPI or the general-purpose input and output (GPIO) pins to support higher speed data rates.

The device features a 16-bit, Σ-Δ analog-to-digital converter (ADC) and a 14-bit digital-to-analog converter (DAC). The AD74115 contains 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 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.

Product Detail

The EVAL-AD74115-ARDZ is a fully featured evaluation board that can be used to evaluate the features of the AD74115 in a full system solution where power and isolation are provided by the ADP1034. The AD74115 is a single-channel, software configurable, input and output device. The device has functionality for analog output, analog input, digital input, digital output, thermocouple measurement, and 2-wire, 3-wire, and 4-wire resistance temperature detector (RTD) measurements integrated into a single-chip solution with a compatible serial peripheral interface (SPI).

The EVAL-AD74115-ARDZ can be controlled via a system demonstration platform (SDP) board. The EVAL-SDP-CK1Z (SDP-K1) board allows the EVAL-AD74115-ARDZ to be controlled via the USB port of a PC using the AD74115 evaluation software. The EVAL-AD74115-ARDZ requires an operating supply of 4.5 V to 60 V. The PC provides power to the SDP-K1 board.

For full details on the AD74115 and ADP1034, see the AD74115 and ADP1034 data sheets, which must be consulted in conjunction with the user guide when using the EVAL-AD74115-ARDZ.
