13 The AD74412R and AD74413R are quad-channel software configurable input/output
15 functionality for analog output, analog input, digital input, resistance
18 The devices feature a 16-bit ADC and four configurable 13-bit DACs to provide
19 four configurable input/output channels and a suite of diagnostic functions.
20 The AD74413R differentiates itself from the AD74412R by being HART-compatible.
