AD1580
The AD1580 is ideal for creating the reference level to use with 12-bit
multiplying DACs, such as the AD7943, AD7945, and AD7948.
In the single-supply bias mode (see Figure 26), the impedance
seen looking into the I
the AD1580 drives I
of additional linearity error results. The buffer amp eliminates
any linearity degradation that could result from variations in
the reference level.
