The AD3530/AD3530R (8-channel) and AD3531/AD3531R (4-channel) are low-power,
16-bit, buffered voltage output digital-to-analog converters (DACs) with
software-programmable gain controls, providing full-scale output spans of 2.5V
or 5V for reference voltages of 2.5V. These devices operate from a single 2.7V
to 5.5V supply and are guaranteed monotonic by design. The "R" variants
include a 2.5V, 5ppm/°C internal reference, which is disabled by default.

Say yes here to build support for Analog Devices AD3530R, AD3531R
Digital to Analog Converter.
Say yes here to build support for Analog Devices AD3530/AD3530R,
AD3531/AD3531R, and AD3532/AD3532R Digital to Analog Converters.

To compile this driver as a module, choose M here: the
module will be called ad3530r.
