3.7 AIN & VREF Sampling Structures
The CS5581 uses on-chip buffers on the AIN and the VREF+ inputs. Buffers provide much higher input
impedance and therefore reduce the amount of drive current required from an external source. This helps
minimize errors.
The Buffer Enable (BUFEN) pin determines if the on-chip buffers are used or not. If the BUFEN pin is
connected to the V1+ supply, the buffers will be enabled. If the BUFEN pin is connected to the V1- pin,
the buffers are off. The converter will consume about 30 mW less power when the buffers are off, but the
input impedances of AIN, ACOM and VREF+ will be significantly less than with the buffers enabled.
3.8 Converter Performance
The CS5581 achieves excellent differential nonlinearity (DNL) as shown in Figures 9 and 10. Figure 9
illustrates the code widths on the typical scale of ±1 LSB. Figure 10 illustrates a zoomed scale of ±0.1
LSB. The DNL error histogram in Figure 10 indicates that more than half the codes are accurate to better
than ±0.01 LSB.
