13   The AD74412R and AD74413R are quad-channel software configurable input/output
17   into a single chip solution with an SPI interface.
18   The devices feature a 16-bit ADC and four configurable 13-bit DACs to provide
20   The AD74413R differentiates itself from the AD74412R by being HART-compatible.
