16-Bit Single-Supply Buffered Voltage Output Digital-to Analog Conversion with Less Than В±1 LSB Integral and Differential Nonlinearity (CN0348)

The circuit in Figure 1 is a complete single-supply,16-bit buffered voltage output DAC that maintains ±1 LSB integral and differential nonlinearity by utilizing a CMOS DAC followed by an innovative amplifier that has no crossover distortion.


The circuit eliminates the crossover nonlinearity associated with most rail-to-rail op amps that can be as high as 4 or 5 LSBs for a 16-bit system.


This industry-leading solution is ideal for industrial process control and instrumentation applications where a compact, single-supply, low cost, and highly linear 16-bit buffered voltage source is required.


Total power dissipation for the three active devices is less than 25 mW typical when operating on a single 6 V supply.
