14-Bit DACs Maintain High Performance over Extended Temperature Range -  AN-314 Analog Devices Application Notes

16-bit adjustable reference uses 8-bit digital potentiometers -  25-Dec-03 Issue of EDN  It may be easy to find a precision voltage reference for your application; however, a programmable precision reference is another matter. The circuit in Figure 1 yields a precision reference with an LSB of 62.5 µV. The circuit is a 16-bit DAC using three 8-bit digital potentiometers and three CMOS op amps....

2 DAC Circuit Adds & Subtracts -  09/01/98 EDN-Design Ideas  A typical way to add two binary words and provide an analog output is to use several digital ICs that drive a DAC. The circuit in Figure 1  eliminates the use of several digital-IC packages and, hence, the need for the digital power supply. The circuit simultaneously carries out addition and subtraction….File has many circuits, scroll down…. [Design Idea by V Manoharan, Naval Physical and Oceanographic Laboratory, Kochi, India]

µC reprograms audio DAC via serial interface -  01/07/99 Issue of EDN  You can use a simple µC to continuously program an audio DAC so that it operates in a 20-bit resolution mode ( Figure 1 ]. After power-on,  PCM1710 delta-sigma DAC (Burr-Brown Corp, www.burr-brown.com]operates in its default 16-bit resolution....Page includes several designs.  Scroll to find this one....
