Each output channel in the DACx1416 consists of an R-2R ladder architecture followed by an output buffer amplifier capable of rail-to-rail operation. The output amplifiers can drive 25 mA with 1.5-V headroom from either V_CC or V_SS while maintaining the specified TUE specification for the device. The full-scale output voltage for each channel can be individually configured to the following ranges:

• –20 V to +20 V
• –10 V to +10 V
• –5 V to +5 V
• –2.5 V to +2.5 V
• 0 V to 40 V
• 0 V to 20 V
• 0 V to 10 V
• 0 V to 5 V

Figure 8-1 shows a block diagram of the DAC architecture.
