All static performance tests (except IOUTx) are performed in a closed-loop system using an external precision OP177 I-to-V converter amplifier. The AD5544 RFB terminal
is tied to the amplifier output. 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 AD8038 I-to-V converter amplifier.
