ADC1610S series

Single 16-bit ADC; CMOS or LVDS DDR digital output

Figure 21 to Figure 24 illustrate how to connect the SENSE and VREF pins to select the

required reference voltage source.

11.3.2 Programmable full-scale

The full-scale is programmable between 1 V (p-p) to 2 V (p-p) (see Table 13).
