The 205l Direct makes use of the 2510 and 2520 op-amps and therefore exhibits the reliability, long life, and uniformity characteristic of API products.
Why so many OP-Amps in the DAC1? The answer is that the DAC1 USES parallel signal paths to keep the total number of OP-Amps to a minimum in any given path.
