All static performance tests (except I
OUT
) are performed in a closed-loop system, using an external precision OP97 I-V converter amplifier. The AD554x RFB terminal is
tied to the amplifier output. The op amp +IN is grounded and the DAC I
OUT
is tied to the op amp –IN. Typical values represent average readings measured at 25°C.

These parameters are guaranteed by design and not subject to production testing.
3
All input control signals are specified with t
R
= t
F
= 2.5 ns (10% to 90% of 3 V), and timed from a voltage level of 1.5 V.
4
All ac characteristic tests are performed in a closed-loop system using an AD841 I-V converter amplifier.
