PRODUCTION DATA
The resistor string structure is shown in Figure 7-10. The resistor string consists of a string of resistors, each of value R. The code loaded to the DAC latch determines at which node on the string the voltage is tapped off to be fed into the output amplifier. The voltage is tapped off by closing one of the switches connecting the string to the amplifier. This architecture is inherently monotonic, voltage out, and low glitch. The resistor string architecture is also linear because all the resistors are of equal value.
