AD74115HBCPZ

AD74115HBCPZ is a single channel, software configurable input and output with HART modem. It provides a wide range of use cases, integrated on a single chip. This uses cases include analogue output, analogue input, digital output, digital input, resistance temperature detector (RTD), and thermocouple measurement capability. It also has an integrated HART modem. A serial peripheral interface (SPI) is used to handle all communications to the device, including communications with the HART modem. 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 16bit, Σ-Δ analogue-to-digital converter (ADC) and a 14bit digital-to-analogue converter (DAC). Application includes isolated industrial control systems, process control, factory automation, building control systems.
