The AD74416H is a quad-channel, software configurable, input and output device for industrial control applications. The AD74416H provides a wide range of use cases integrated on a single chip. These use cases include analog input/output, digital input/output, resistance temperature detector (RTD), and thermocouple measurement capability.
The AD74416H also has an integrated highway addressable remote transducer (HART) modem per channel. The input and output communications and the HART communications for all four channels are both supported using a single serial-peripheral interface (SPI).
The AD74416H provides two address pins to support up to four devices with a single SPI bus. The digital input/outputs can be accessed by the SPI or the general-purpose input/output (GPIO) pins to support higher speed data rates.
The AD74416H features a 16-bit digital-to-analog converter (DAC) per channel and a single 24-bit, Σ-Δ analog-to-digital converter (ADC). The AD74416H contains a high accuracy 2.5V on-chip reference that can be used as the DAC and ADC reference.
The AD74416H supports adaptive power switching, which allows the output stage to dynamically transition between two independent power sources. This transitioning ability saves up to 40% overall power consumption, thereby reducing dissipated heat in the module.
