 ===== Introduction =====
-The [[adi>AD9116]] is a 12-bit, low power digital-to-analog converter (DAC) that provides a sample rate of 125 MSPS. This TxDAC converter is optimized for the transmit signal path of communication systems. The AD9116 offers exceptional AC and DC performance and supports update rates up to 125 MSPS. The flexible power supply operating range of 1.8V to 3.3V and low power dissipation of the AD9116 makes it well suited for portable and low power applications.
+The [[adi>AD9114]]/[[adi>AD9115]]/[[adi>AD9116]]/[[adi>AD9117]] are pin-compatible dual, 8-/10-/12-/14-bit, low power digital-to-analog converters (DACs) that provide a sample rate of 125 MSPS. These TxDAC® converters are optimized for the transmit signal path of commu-nication systems. All the devices share the same interface, package, and pinout, providing an upward or downward component selection path based on performance, resolution, and cost.
+The AD9114/AD9115/AD9116/AD9117 offer exceptional ac and dc performance and support update rates up to 125 MSPS.
+The flexible power supply operating range of 1.8 V to 3.3 V and low power dissipation of the AD9114/AD9115/AD9116/AD9117 make them well suited for portable and low power applications.

+The User Interface is divided in 13 sections, described below:
+  - **Section 1** Communication with the board is activated / deactivated by toggling the ON/OFF Switch
+  - **Section 2** Modifies data format sent to the AD911x by toggling the switches ON or OFF:
+      * DATADIR sets the transmission mode (ON = LSB First, OFF = MSB First)
+      * LNGINS sets the number of address bits used by the Instruction Word (ON = 13 bits, OFF = 5 bits)
+  - **Section 3** Modifies the way data is received from the DDS Module:
+      * TWOS sets the input data format (ON = Twos complement, OFF = Unsigned Binary)
