The ADC outputs go to a digital processing block that can be used to enhance ADC performance. Some of the operations done in the digital processing block can enhance the effective signal to noise ratio at its output. For this reason, the number of bits at the DIGOUT1 to DIGOUT16 signals are considered to be 16. However, some of the LSBs of this 16-bit word may be zero. For example, when the digital processing block is bypassed, the number of non-zero bits in DIGOUT is the same as the ADC resolution—the extra LSBs of the 16-bit word are zero.
The digital processing block results in additional latency that can be avoided by using the low latency mode (programmed using the LOW_LATENCY_EN bit) that bypasses the entire digital processing block without introducing extra latency. The various features available in the digital processing block are shown in Figure 62 and are explained in the subsequent sections.
