NOTES

1All static performance tests (except I

OUT) 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.

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

3All input control signals are speciﬁed with t

R = 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.
