NOTES:
1All static performance tests (except IOUT) are performed in a closed-loop system using an external precision OP177 I-to-V converter amplifier. The AD5554
RFB terminal is tied to the amplifier output. Typical values represent average readings measured at 25 °C.
2These parameters are guaranteed by design and not subject to production testing.
3All 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.
Specifications subject to change without notice.
