This DAC uses a multi-bit A/D converter to sample the Digital Word and performs successive approximations to calculate the corresponding analog voltage and produces the analog output voltage.The DAC uses an internal reference voltage to compare the approximated values of the Digital Word with the actual analog voltage and then adjusts the output to the right value. This process is repeated until the required accuracy is achieved and the DAC eventually produces an analog voltage that is equal to the Digital Word stored in the register.

Conclusion

The LTC2657BCUFD-H16#PBF is a highly accurate and reliable data acquisition - digital to analog converter (DAC).
