1 All static performance tests (except IOUT) 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 IOUT is tied to the op amp –IN. Typical values represent average readings measured at 25°C.

2 These parameters are guaranteed by design and not subject to production testing.

3 All input control signals are specified with tR = tF = 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.
