1 All static performance tests (except IOUT) are performed in a closed-loop system using an external precision OP97 I-to-V converter amplifier. The device RFB terminal is
tied to the amplifier output. The +IN pin of the OP97 is grounded, and the IOUT of the DAC is tied to the OP97’s IN pin. Typical values represent average readings
measured at 25°C.
2 Guaranteed by design; 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 are timed from a voltage level of 1.5 V.
4 All ac characteristic tests are performed in a closed-loop system using an AD8038 I-to-V converter amplifier except for THD where the AD8065 was used.
