All static performance tests (except IOUT) are performed in a closed-loop system using an external precision OP177 I-to-V converter amplifier. The AD5543 RFB terminal is

tied to the amplifier output. The +IN op amp is grounded, and the DAC IOUT is tied to the −IN op amp. Typical values represent average readings measured at 25°C.

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

All ac characteristic tests are performed in a closed-loop system using an AD8038 I-to-V converter amplifier except for THD where an AD8065 was used.

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.
