The AD74414H is a quad-channel, software configurable, input and output device for industrial control applications. The AD74414H provides a range of use cases integrated on a single chip. These use cases include analog input/output and digital input/output. The AD74414H 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 AD74414H provides two address pins to support up to four devices with a single SPI bus. SPI or general-purpose input/output (GPIO) pins can access the digital inputs/outputs to support higher data rates.
The AD74414H features a 14-bit digital-to-analog converter (DAC) per channel and a single 16-bit, Σ-Δ analog-to-digital converter (ADC). The AD74414H includes a high accuracy 2.5V on-chip reference that can serve as the DAC and ADC reference.
The AD74414H 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.
